1. Brief description. The Synchrotact 5 digital synchronizer is used for automatic synchronizing and paralleling of generators with lines and for the paralleling of already synchronous lines. The device is designed for system frequencies of either 50/60 or 16 2/3 Hz. Syn 5201 is a single channel synchronizing device whose component choice and software design provides the highest security against incorrect paralleling. Syn 5202 consists of two independent channels with different hardware and software. This dual-channel property maximizes security against incorrect paralleling. All parameters required for paralleling are stored in parameter set.The paralleling conditions and the characteristics of the voltage and frequency matchers are defined in this set.With the option providing seven parameter sets, paralleling can be carried out under different conditions or with different matcher charactristics using the same devices.Seven configurable digital inputs and outputs are available for the selection and back indication of parameter set. The data which are important for commissioning and for control purposes can be uploaded or downloaded using the PC tool SynView or, alternatively via the keypad on the front panel of the unit. 2. Warning and Instructions :

Synchrotact 5 devices operate with in some cases dangerous voltages (>50 V), e.g measuring inputs up to 170 VAC & relay outputs up to 250 VAC/VDC. Manipulations carried out on these parts can cause death or injury to the persons envoirment, as described in these instruction , there is no risk.

All relevant regulations must be observed during commissioning. It is essential that these safety regulations are read before starting any work on the Synchrotact 5 equipment.

After the devise has been switched off, it must be insured, by measuring, that no measuring voltage or control voltages >50 V are present at the teriminals before anything is done to the device itself, e.g. unplugging the connector to replace the device. In order to prevent open voltage cuircut being accidentally closed by third parties, the cuircut in question should be marked at the disconnection point (e.g. with warning sign).

If work is being carried out in the envoirment of the Synchrotact 5, e.g. on the relay controls, electronics power supply, synchronizing instruments, all voltages greater that 50 V which are connected to the system must be switched off.

Caution: Before switching on, always check whether all connectors are plugged in.

Caution: The device may only be opened by qualified personnel. It is essential that ESD regulations are complied with.

3. Test equipment.

1. PC tool software Synview 3.1.(Available in QC server) 2. RJ45 ethernet cable. 3. Lap top. 4. Freja 300. 5. Synchrotact 5 simulation kit made by QC. 6. Multimeter. 7. Testing Leads. 8. Timer TM200.

4. Synchrotact 5 (SYN 5201) configuration: 1. Start the SynView program & Power up the relay. 2. Connect the RJ45 Ethernet cable from Relay to PC. 3. To know the IP address of the Synchrotact relay follow the instruction below.

For example it will display IP address : 192.168.0.250 Subnet mask:255.255.255.0 Gateway : 0.0.0.0 Set IP address of the PC with respect to the Relay IP address.(For eg: 192.168.0.249) Select OptionsCommunication Then Select interface as Communication Over TCP/IP and select OK.

4


Now select ToolsParameter. If communication is not ok then the following error message will be displayed.

5


If the communication is Ok it will display the settings page as below.

Once every things are ready , you can switch on the testing kit Freja 300 & make the relay in ready state & Intiate the starting signal , the Relay will start supervise the criteria ΔU , & S & if its matching with the setting , the relay will give a close command (X6:1 & 2) .

After you complete all the configurations save it & press write to transfer all the data to Sychrotact 5 Relay.

For Dead Bus Testing : Dead Bus relaese Binary Input should be activated before giving the start signal otherwise the relay will not give the closing signal & after some time it will give Block/Error Indication. Testing of Synchrotact 5 : Refer to the test formof Synchrotact 5 relay . For all of the test , you should give a start signal to the Synchrotact relay. 5.1 Testing of Paralleling Conditions.

5.5 Lead AngleTest.

For Asynchronous sources paralleling:

1. By using SynView transient recorder tool or connect external recorder (CH1:U1-U2, CH2 paralleling command (=trigger)) .

2. Sypply two voltages with different frequencies (inside slip tolerance band). 3. Start synchronizing process till the paralleling command was given. 4. The lead angle can be calculated from the time ton , between paralleling command and

phase coincidence (read it from the transient recorder picture). 5. Lead angle (Degree)=3.6*fn(Hz)*slip (%)*ton (Sec.).

For Asynchronous sources paralleling:

1. Supply two voltages with the same frequencies but with different phase angle (inside angle window).

2. Start syncronizing process till the paralleleing command was given.
