1.0 Product Introduction

The RD-33 Portable Three-phase Electricity Standard utilizes a lightweight, compact package while providing a high level of accuracy through design innovations. The RD-33 has a guaranteed accuracy of 0.01%. This specifi cation includes variables of stability, temperature, power factor, traceability uncertainty, and test system errors. In addition, this accuracy applies across the entire voltage and current operating range of the product for one year.

The RD-33 utilizes Radian’s new Dytronic measurement technology consisting of a Radian designed Integrating Analog to Digital Signal Converter. The RD-33’s Dytronic A/D Converter is combined with Radian’s renowned electronically compensated voltage and current input transformers and a hermetically sealed reference set to provide the highest degree of accuracy, stability and versatility offered in a portable three-phase electricity standard.

The RD-33 provides four quadrant three-phase simultaneous measurements for active, reactive, and apparent energy and power with forward and reverse energy fl ow also measured. The potential input, current input and auxiliary power input are totally autoranging. This autoranging feature was pioneered by Radian Research and makes it impossible to damage the unit by applying a signal to the wrong tap. The potential input range is 30 to 630 volts, the current input range is available as either 120 amps or 200 amps per phase. The auxiliary power ranges from 60 to 630 volts.

In the fi eld, the RD-33 can be used with a controlled current load, or it can be used with clamp-on current transformers available from Radian Research to perform customer load tests. In this fi eld application, the optional power analysis capability can analyze customer load through the 200th harmonic order. In addition, for improved effi ciency, the RD-33 optionally can automatically calculate and display the error of the meter under test.

In addition, the RD-33 can analyze harmonic distortion complete with each order’s phase and amplitude. This information can be studied in the laboratory with Radian software for a more complete understanding of conditions at specifi c meter installations. Additionally, voltage and current waveforms can be viewed in real-time and then captured for later investigation. Test results of both revenue billing meters and fi eld standards can be stored enabling complete and detailed histories to be recorded.

Clamp On Current Transformer InputThe RD-33 features a clamp-on current transformer input per phase. This option allows true customer load testing without removing the meter from service.

Voltage Inputs, Current Inputs, Auxiliary Power InputsThe RD-33 provides full autoranging capability for the Potential Input, Auxiliary Power Input and Current Input using electronically compensated input transformers designed by Radian. The voltage and current inputs contain an enhanced design of Radian’s original electronically compensated transformer. This feature ensures the unit will never be damaged by applying a signal to the incorrect input. Current input options are 120 amps maximum per phase or 200 amps maximum per phase direct connection.

With the safety of the user in mind, the connections are of an insulated socket design. The Potential Input and Auxiliary Power are 4mm connections and the Current Inputs are 6mm connections for the 120 amp model and bolt-on high current carrying capcity connections for the 200 amp model.

1.2 Laboratory ApplicationsThe accuracy and precision provided by the RD-33 allows it to easily test portable fi eld standards of lesser accuracy. The optional built-in comparator allows for automatic test result calculations for the fi eld standard being tested.

1.3 Test Table ApplicationsDue to its small package size, the RD-33 can easily be used as the reference within test tables whenever a higher level of accuracy is desired. Programmable pulse outputs coupled with an RS-232 communications port make it easy to receive data from the RD-33.

1.4 Field Testing ApplicationsWith a weight of only 6.81 kg (15 pounds), the RD-33 is conducive to fi eld-testing applications where a high level of accuracy is desired. The optional built-in comparator allows for automatic test result calculations of the meter being tested.

1.5 Power AnalysisUnlike off-the-shelf A/D Converters used in other instruments, Radian’s Dytronic A/D Converter is specifi cally designed and optimized for power and energy measurement. This unique design allows the RD-33 to accurately measure non-sinusoidal waveforms up to and including the 200th harmonic order. Measurement parameters include the phase and amplitude of each harmonic as well as the total harmonic distortion. The unprecedented accuracy of measuring distorted waveforms combines with this optional power analysis capability to clearly distinguish the RD-33 as the defi nitive portable three-phase electricity standard for both meter testing and power quality applications. This power analysis option is also useful when testing meters using customer load.

1.6 Customer Load TestingFor those applications where meter testing with customer load is desired, the RD-33 is an obvious choice because of its ability to accurately measure energy and power even with distorted waveforms. The optional clamp-on current transformer inputs on each phase allows for testing the meter using customer load without the need to interrupt service.

1.7 Automatic CalculationsOptionally, the RD-33 offers a built-in computer for two types of applications. For laboratory applications, the built-in computer can accept output pulses from a portable fi eld standard and automatically calculate and display the error. For fi eld-testing applications, it can also automatically calculate and display the error of the meter under test. In this fi eld-testing application, various sensors (for disk rotation, infrared calibration pulses, KYZ pulses, etc.) may be connected directly to the RD-33 and parameters for the test may be easily entered. At test conclusion, the results are automatically calculated and displayed on the RD’s LCD display. Optional sensors include the RR-DS Meter Disk Sensor, RR-1H Infrared Optical Pickup, RR-1H/v Visible Optical Pickup, and RR-KYZ Pulse Input Adapter.

1.8 Software PackagesThe RD-33 also provides a serial communications port which allows direct connection to the RS-232 serial port of a personal computer. In addition, Radian offers software packages to suit various applications.

RR-PCSuite software allows for custom confi guration of the RD-33 standard. This custom confi guration includes defi ning scrolling sequences, scrolling times, defi ning communication ports including output pulse values, defi ning measurement displays, and other operation parameters.

RR-MobileSuite software is used with the power analyzer functionality of the RD-33. RR-MobileSuite provides the ability to view current and voltage waveforms in real time while providing total harmonic distortion as well as analysis of harmonic order, phase and amplitude. Waveforms may be saved for further analysis and record keeping.



10

RR-Kit software provides a library of subroutines for those customers that desire to write their own programs to communicate with the RD-33.

PC-Mobile Suite software is an expanded, desktop or laptop version of RR-Mobile Suite which is the test and measurement software loaded on the RD-33.

1.9 Safety DesignFor enhanced safety, the potential, current and auxiliary power input connections to the RD-33 are designed such that no harmful signals are accessible on the front of the standard. Lead kits may be purchased from Radian Research.

Operations Overview Operations Overview

4.0 Operations Overview

4.1 Measurement PrincipleThe RD-33 measurement principle is based upon the fundamentals of a high-speed charge-balance integrating analog to digital signal converter. This is a Radian innovation, but it is based upon accepted metrology parameters. Radian Research implemented its own analog to digital converter in the Dytronic family of standards which are specifi cally designed for power measurement. In order to measure power and energy with extreme accuracy and wide bandwidth, extensive requirements must be imposed on the converter.

The RD-33 Dytronic utilizes two separate A/D converters. One accepts a current signal and is linked with two current references. The other accepts a voltage signal and is linked with two voltage references. These of course are for the analog voltage and current inputs of the RD-33. Both operate independently to provide the digital signal processor with signals accurate enough to meet the requirements of a true portable electricity standard.

By designing an analog to digital converter specifi cally for power and energy measurements, Radian is able to reduce many errors associated with commercial A/D circuits. Gain error, charge timer resolution, signal to noise ratio and signal distortion were major areas dealt with and improved in development.

4.2 Internal Reference SetThe RD-33’s internal reference set is hermetically sealed in order to protect it from environmental variables. The internal reference set consists of a voltage reference, a resistive reference and a crystal time reference.

4.3 Display and Pulse Output The RD-33 displays the measurements and provides pulse outputs for the selected measurements. Computer control, with Radian software, allows for customization of output information, such as programmable pulse output constants.



18 * Appendix: RD Current Connector Locking Mechanism...... page 73

4.4 Voltage and Current InputsThe voltage and current inputs are completely autoranging – a design feature that was pioneered by Radian Research with the RM-10 in 1985. The voltage and current inputs consist of a toroidal autoranging electronically compensated transformer which reduces the need for switching relays that can prove unreliable over time. The specially designed and manufactured Radian toroid transformer provides superior immunity to stray fi elds while electronic compensation eliminates practically all of the transformer error.

4.5 Auxiliary Power InputsAuxiliary power is required to power the RD-33’s measurement circuits. Power may be derived from the same signal as the potential input providing that there are suffi cient volt-amperes avail-able. Auxiliary power may also be supplied independent from the potential input source. The power supply for the RD-33 is a very advanced switching power supply which is inherently ca-pable of converting the available input power to regulated power over the entire operating range. The converter is so effective at this that the input may be changed freely between the ranges of 60 and 630 VAC during operation without a measurable effect upon operation.

The connections have been updated to an insulated socket design. The Potential Input and Aux-iliary Power Input are 4mm connections and the Current Inputs are 6mm connections (bolt-on design for 200 amp models).*

Model RD-33-337



19

4.6 Clamp-On CT InputThe RD-33 features a clamp-on current transformer input. This input can only be utilized with Radian approved current transformers, as others do not have the inherent accuracy needed to optimize the RD-33’s accuracy and stability. The input is a seven-pin connector that provides power, serial communications, and an input for specifi c clamp-on current transformers.

4.7 Pulse InputsThe RD-33 Pulse Inputs consist of BNC connectors labeled 1, 2, 3. These inputs are open col-lector. Phase A input is labeled as 1, Phase B input is labeled as 2 and Phase C input is labeled as 3. While performing a meter test the RM-1S Remote Reset Switch may be connected to input 3 (Phase C input) and can be used to gate (start/stop/reset) all three inputs simultaneously. Alter-natively, any of the available Radian pickups may be connected to input 3 (Phase C input). The pickups consist of the RM-1H, RM-DS, and RM-KYZ, all which can be used to test various electricity meters. While performing a standards test all three inputs can be used individually or simultaneously.

4.9 Analog Sense InputThe optional Analog Sense functionality allows the RD-33 to effectively test transducers as well as fi rst generation electronic meters that have an analog output for calibration. The RD-33 will not only test these instruments, but it will also automatically calculate and display the error.

4.8 Pulse OutputsThe RD-33 Pulse Outputs consist of BNC connectors labeled 1, 2, 3. These outputs are open collector. The factory default setting is Output 1 = Total Watthours, Output 2 = Total VARhours, Output 3 = Total VAhours. However all three outputs are programmable by the customer for per phase energy or total energy.

Communications Protocol

Half duplex RS-232 57.6k Baud 1 start bit, 1 stop bit, no parity DTR line high After the RD has received a packet, an acknowledgment (ACK) is transmitted indicating

the status of the packet. The time between the receipt of any packet by the RD-xx and the transmission of an ACK is typically less than 50 mS and worst-case 225 mS.

The PC or other controlling device (host) operates as the master and the RD-xx operates as the slave.

More information and commands for communication are available in the RD-Kit custom application development software package.

4.10 Serial Port Communications TerminalThe communications terminal is interfaced via a DB-9 connector. Through the use of this terminal, a myriad of capabilities present themselves. Not only can each RD-33 software package be utilized, the RD-33 can actually be re-calibrated through this terminal. Additionally, the fl ash memory storage for both the DSP and Xilinx programs is accessible through this terminal making the RD-33 fi eld upgradable.

4.12 Chassis Ground, Guard, NeutralChassis Ground – ideally tied to the best available earth ground. If the RD-33 is mounted in a rack, no connection is required. The Chassis grounds main purpose is for safety.

4.11 Pickup TerminalThe sensor input terminal on the RD-33 comes in the form of a 4 Pin Lemo connector. Radian Disk sensors, infrared and visible LED optical pickups can be utilized to sense disk rotation or equivalent revolutions if the built-in comparator functionality is supported. See Section 2.1 Generating RD-33 Model Numbers for further information.

Guard – should be tied to the common of the Wye source for Wye usage and left to fl oat in Delta use applications. Because the Analog Sense is common with the Guard ground, care must be taken to avoid ground loop problems.

V1, 2, 3 / VN – the three VN connections should be tied together, via twisted wire pair, with their as-sociated Potential Inputs (V1, V2, V3). At the Device Under Test (DUT), each VN should be broken out from its associated twisted wire pair and each tied to the DUT Neutral with the three Potentials (V1, V2, V3) tied to the three Potential connections of the DUT. The three Potentials (V1, V2, V3) of the DUT should be tied to the associated three Potentials of the source. If using a Wye source, the Neutral from the DUT, containing the three VNs, should be tied to the Wye source neutral. If using a Delta source, the DUT Neutral, containing the three VNs, should be allowed to fl oat.

5.0 Service & Routine Maintenance

The RD-33 Dytronic portable electricity Standard is virtually maintenance free. The elimination of all contacts, switches and tap selections on the primary side of the input transformers signifi cantly improves reliability by eliminating both service components and the opportunity for operator error. Other than cleaning of the outside surface and the yearly recalibration, no routine maintenance is required.

5.1 CleaningCleaning of the RD-33 may be performed with a clean, dry lint-free cloth dampened slightly with a mild non-abrasive cleaner. The area around the top terminals should be buffed dry with another clean and totally dry cloth.

5.2 RepairDue to the instruments complexity and use of surface mount component it is recommended that Radian Research perform all repairs. We have excellent automated testers with which every internal module can be tested quickly to original factory specifi cations. A fi nal calibration and quality control inspection to original factory specifi cations is performed quickly and thoroughly. If the RD-33 should require repair then contact Radian Research or your local Radian Research Representative and request a Return Material Authorization (RMA) number. You must provide the model number and serial number as well as a detailed description of the problem.

5.3 RecalibrationRecalibration is recommended yearly. A periodic cross check against a Radian RD-21 or RD-22 or RD-33 is recommended to preclude the possibility of a failure in either. Prudence would dictate having a dedicated RD-21 or RD-22 or RD-33 for cross check purposes. With the RD-21 or RD-22 or RD-33 it is feasible to sample test units at various points as a “backup” test. In addition, it is recommended that one take advantage of Radian’s recalibration service as a very cost effective method to maintain traceability. Radian Research’s Calibration Laboratory maintains primary transfer standards that are directly traceable to NIST. Radian Research’s Calibration Laboratory also maintains several RS-703A Automated Calibration Systems as working secondary standards.

The RS-703A Automated Calibration System collects a data point on a RD Radian standard every 5 (fi ve) seconds on up to sixteen standards simultaneously, collecting literally thousands of data points on an overnight run. In addition each RS-703A provides computer control over an environmental chamber to ensure proper temperature range operation of the standard being tested. Please contact Radian Research for further information on recalibration and recertifi cation services.

5.4 Fuse ReplacementIn the unlikely event of fuse replacement, fuses are included and are accessible without disassem-bly. There are four fuses: three potential input and one auxiliary power. All fuses are located under the red potential and auxiliary power inputs. Fuse replacement is performed as follows:

1. Remove the red terminal of the circuit with bad fuse by rotating 90o counter- clockwise and then lift out the unit.2. Remove the fuse by rotating it clockwise in the retaining screw.3. Replace the fuse by rotating it clockwise in the retaining fuse.4. Replace the terminal in the same orientation it was removed and rotate it 90o clockwise to lock in place.

Step 3Using the stylus, single tap on the Run Meter Test icon. The meter test screen will now appear (see Section 8.8)

Step 4Use the onscreen keyboard (see Section 8.10) to enter the DUT serial number.


Note: If performing KYZ testing, the meter’s Ke factor should be entered in place of a Kh value. Ke is the watthour pulse constant of each pulse from the pulse initiator (KYZ). The value of the Ke is dependent upon the meter Kh and the type of test conducted. The Ke factor of any meter may be calculated by using the following constants.

Kh = Watthour constant. The number of watthours represented by one revolution of the disk. Also called the disk constant.

Mp = Number of revolutions per pulse

Example Calculation:

Ke = (Kh) x (Mp); if Kh = 1.8 watthours per revolution and Mp = 1 revolution per 12 pulses, then,

Ke = (1.8 Wh/1 rev) x (1 rev/12 pulses) = (1.8 Wh/12 pulses) = 0.15 Wh/pulse

Step 6Use the stylus and the arrow keys on the Meter Test screen to enter/select the Pulses per Kh, # Seconds or Pulses, DUT Elements, Test Type, Standard Elements, Phase and State. Repeat Step 6 for all applicable DUT(s).

Note: If performing KYZ testing, enter one pulse per Ke value.

Once complete, the Percent Registration, Percent Error, Test Status, Metric Value, Function Tested, Minimum Percent Registration, Minimum Percent Error, Minimum Percent Pulses, Minimum Percent Metric, Standard Deviation of Percent Registration, Standard Deviation of Percent Error, Standard Deviation of Number Pulses and Standard Deviation of the Metrics being tested are reported.


11.2 Standards TestingThe RD-33 can be used in the fi eld or in the laboratory to test one (1), two (2) or three (3) single phase standards or one (1) three phase standards where a high degree of accuracy is required. The standards test may be achieved by counting a designated number of pulses from the input port(s) or by counting the number of pulses from the input port(s) over a designated amount of time. The input ports can be confi gured to accept either Radian Research or non-Radian Research standards.

Step 1Make all appropriate connections (see Figure 10.5) so the Device(s) Under Test (DUT) and RD-33 are powered by the same source.

12.0 Test Accessories

RR-DS Meter Disk SensorThe RR-DS is a refl ective pickup assembly used to sense the disk rotation of an induction type meter. The pulses generated by the RM-DS are fed into the PICKUP port of the RD-33. Evalu-ation of different types of meter designs is fully automated when the Built-in Computer option is utilized. The RR-DS is available in two (2) different mounting options. The RR-DS/f Disk Sensor with Field Mount features a Velcro strap that attaches around the meter cover. This allows the sensor to sense disk rotation from the side of the meter. The RR-DS/sm Disk Sensor with Suction Mount features an L-bracket with three (3) suction cups that attach to the front of the meter cover. This allows the sensor to sense disk rotation from the front of the meter.

RR-1H Optical Pickup for Infrared LEDThe RR-1H is used to sense the infrared pulses from the calibration LED of solid-state meters. The pulses from the RR-1H are fed into the PICKUP port of the RD-33. Evaluation of different types of meter designs is fully automated when the Built-in Computer option is utilized. The wide angular displacement of this sensor allows for fast, non-critical alignment. Also, automatic gain control circuitry of the RR-1H assures operation in all ambient sunlight conditions. The RR-1H/v is available for those solid-state meters with a visible calibration LED, and terminates in a BNC Connector instead of a lemo connector. Therefore, the RR-1H/v attaches to port 1 instead of the pickup terminal.

RM-OA Optical AdapterThe RM-OA Optical Adapter is used with solid-state meters whose infrared calibration pulse is emitted from the optical communications port. The RM-OA magnetically couples to the com-munication port of solid-state meters. The suction cup of the RD-1H is attached to the clear polycarbonate cover of the RM-OA. The RM-OA incorporates a rare earth permanent magnet for exceptional holding power over the life of the product.

RR-KYZ Pulse Input AdapterThe RR-KYZ Pulse Input Adapter is used to sense the KYZ output pulses of induction or solid-state meters. The Pulses received from the meter’s KYZ output are conditioned and fed into the PICKUP port on the RD-33. The testing of KYZ equipped meters is done automatically with the Built-in Computer option of the RD-33.



72

RM-1S Remote Reset SwitchThe RM-1S Remote Reset Switch is a normally closed push button switch. The RM-1S connects directly to Port 1 of the RD-33. The snap switch of the RM-1S is hermetically sealed. The push-button has positive tactile feel to provide instantaneous feedback of the switch action.

RM-Metronic SensorsOlder sensor designs such as the RM-DS Disk Sensor, RM-1H Infrared Optical Pickup, RM-1H/v Visible Optical Pickup and RM-KYZ Pulse Input Adapter can be used with the RD-33, but must be connected to Port 1 because they terminate in a BNC connector

RD Current Connector Locking MechanisimRD Current Connector Locking Mechanisim

Appendix: RD Current Connector Locking MechanismThe Radian RD-2X and RD-3X (120A) Dytronic Standards utilize 6mm locking style connectors for the current inputs.

Note: These connectors are very specialized and feature beveled edges and a locking ring. Do NOT use straight ¼” current connector studs. Radian offers various jumpers and adaptors to fi t most applications.

When connecting to the current inputs, insert the 6mm current plugs slowly into the current input receptacles on the RD standard. Do not use excessive pressure when inserting. Only a minimal amount of force is required to engage the locking mechanism.

NOTE: Pushing the current plug too hard may engage and then disengage the locking mechanism in one move. To prevent this, gently push the plug into the receptacle and allow the lock to engage.

Once the locking mechanism is engaged, pull on the current plug outward. You should NOT be able to remove the plug.
