Product Description

Product Description

IMPULSE VOLTAGE TEST SYSTEM

Generates lightning impulse (1.2±30%/50±20%μs), LI (T1:1~5μs, T2:40~60μs) for cable testing, chopped lightning impulse (chopped time 2~5μs for transformers, instrument/voltage transformers, bushings), switching impulse (250±20%/2500±60%μs), and steep front wave forms (for testing glass, composite, or ceramic insulators).

Specification

Applications

1It is used to test the insulation strength of power equipment (transformers, circuit breakers, insulators, etc.) under impulse voltages like lightning/switching overvoltages, ensuring safe equipment operation in extreme environments.
2.In the production and manufacturing process of electrical equipment, it tests the impulse voltage tolerance of products, screens out unqualified products, ensuring quality and reliability of equipment leaving the factory.

Key Configurations

Energy Storage Capacitor Module: High-insulation, low-loss capacitors, multi-stage series, setting output voltage limit.

Control System: PLC controller + touch screen, manual/automatic modes, setting charging voltage, trigger time, and more.

Charging Circuit System: High-voltage rectifier and charging resistor convert AC to DC high voltage to charge capacitors.

Insulation Support Structure: Epoxy insulation tube, insulator, ensuring insulation between high-voltage part and ground.

Discharge Trigger Device: High-precision sphere gap/electronic switch, precisely controlling discharge timing for waveform stability.
