Lightning impulse voltage generator

Lightning impulse generator ca, generate impulse voltages simulating lightning impulse, chopped lightning impulse, switching impulse and steep front surges. It can test the HV (High Voltage) power transformer, power cable, circuit breaker, GIS, insulator, surge arrester and other electrical equipments.

Lightning generation technology

The 10 pulse (or multi pulse) generator can produce 1-10 lightning impulses. Different waveforms are available from the generator.

Surge current generator for SPD

Surge current generator is applied for testing SPD (Surge Protective Device), varistor, GDT, TVS, lightning rod and other lightning protection devices.

Short circuit current test

This equipment adopts impulse AC transformer, outputting short-time AC high current to test the high current withstand ability, heating effect, power effect, and electrical performance of products under AC high current environment.

AC/DC aging test system

AC/DC aging test system is specially designed to process the aging test and measure the powerloss of MOV.

AC resonant test system

AC resonant test system are applied to HV AC routine, type and development testing of capacitive test objects.

AC test transformer

AC test transformer can generate continuously variable AC test voltage at power frequency. They are designed for testing all types of electrical insulations, especially apparatus in power system such as insulators, switchgear, HV transformers, cables, test lines... They can also be used for research, development and professional training.

SF6 AC test system for GIS/GIL testing

The SF6 transformer based AC test systems operate exactly at power frequency, so that the type of voltage applied for testing and operation is exactly the same. SF6 AC test systems are flanged directly to the test object so that test system and test object are completely encapsulated for a space saving test setup.

Test system for SPD manufacturer

The system solution for SPD manufacturer is a complete "turn-key" package designed for doing all SPD type and routine test.

TOV test system for SPD

The TOV test system is applied for simulating other overvoltage/overcurrent of SPD during its failure in voltage system.

Lightning tower measuring system

The lightning tower is designed for the scientific research of natural lightning characteristics. Lightning tower measuring system is applied for direct measurement and indirect estimation of lightning current parameters, lightning recording, electrical & magnetic field strength measurement.
