PORTABLE TEST EQUIPMENT FROM TETTEX RENOWNED FOR ACCURACY, DURABILITY, AND EASE OF OPERATION

Contact HV TECHNOLOGIES, Inc. for additional product information.

For utility and service companies, electrical maintenance testing is crucial for promoting and maintaining safety. Newconstruction acceptance testing and existing substation maintenance testing are primary factors in prolonging the life of yourelectrical equipment and the ongoing reliability of a utility’s services to their customers. Routine testing of distribution, power,and instrument transformers, bushings, capacitors, circuit breakers, surge arrestors, etc. can be accomplished by usingHaefely / Tettex’s diverse line of portable test equipment.

2293 Winding AnalyzerThe 2293 is an automatic and multipurpose winding analyzer, optimized for 3 phasepower and distribution transformer measurements. It uniquely combines windingresistance measurement, turns ratio measurement, core demagnetization, transformertype detection, magnetic balance, and heat run test (temperature rise and cooling curve)in the fastest single instrument solution on the market.

MIDAS 2881The MIDAS 2881 is a portable power factor tester for periodic maintenance and inspectionof high voltage insulation losses of electrical apparatus, especially in the harsh electricalenvironments experienced in substations and other field locations. Designed for testing atlocal powerline frequency, the MIDAS automatically measures and records dissipationfactor (tan delta), power factor, and all other relevant values of impedances. Damage orchanges in the insulation material are detected rapidly and reliably. The 12 kV highvoltage source and standard capacitor with long-term stability are built into the unit.

MIDAS micro 2883The MIDAS micro 2883 is a revolutionary instrument used to test the insulation of highvoltage components such as transformers, bushings, capacitors, circuit breakers, surgearrestors, etc. This is the smallest and lightest Power Factor / Tan Delta & CapacitanceTester on the market! Weighing at only 55 lbs and housed in a rugged case with casters,this tool can be easily transported to any testing location - whether in the field or on thefactory floor. This unit packs a powerful punch with an integrated 12 kV high voltagesource.

Transformer Turns Ratio MetersTTR 2795 Excitation voltage up to 100 VTTR 2796 Excitation voltage up to 250 VTransformer turns ratio can help to detect faulty transformer windings and defective tapchanger positions. The fully automated 3 phase solutions have unmatched accuracies upto 0.03%.

FRA 5311 Sweep Frequency Response AnalyzerSFRA detects transformer winding movements and mechanical failures due to mechanicalshock, transportation, or short circuits. The FRA 5311 is the smallest and lightest SFRAtester on the market with one single USB connection for data and power to a laptop. Theunit includes a Windows based software with easy to use graphical interface and ability toread test results from other manufacturers of SFRA devices.

RVM 5462 Recovery Voltage MeterThe RVM 5462 Recovery Voltage Meter examines the oil/paper insulation condition inhigh voltage components by tracing the polarization spectrum. This unit is capable ofautomatic measurements of charging voltage, recovery voltage, initial voltage rise slope,peak recovery voltage, time to peak, insulation resistance, polarization index, polarizationcurrent, and interference voltage.

5478 TΩ Meter - Insulation Resistance TesterThe 5478 TΩ Meter is a digital multipurpose tester intended for testing, analyzing,inspecting, and maintaining high voltage insulation. The instrument can supply an outputpower of 5 W and a test voltage of up to 5000 V and therefore is capable of resistancemeasurements up to 5 TΩ.
