Major components help to  measure  HV apparatus for Impulse Voltage Generator

1.The impulse voltage divider is one of the major components of the impulse voltage test system; it can be used to measure the impulse of HV apparatus.

2.The chopping gap is one of the major components of the impulse voltage test system; it can be used for generating chopped wave.

3.The steep front impulse device is one of the major components of the impulse voltage test system; it can be used for generating steep front impulse.

【Other components】

1.The overshoot compensation device helps adjust front time in high capacitive tests. The overshoot compensation device consisting of capacitors and resistors is used to attenuate overshoot and to shorten front time. There are two types of overshoot compensation device by structure: GBD suspending type and GBY mobile type. 

2.The support (voltage limiting) resistor extends the tail time in impulse tests on transformers. It consists of a set of adjustable resistors. 

3.The impulse capacitor consists of a set of grouped capacitors in series. In parallel with test inductors, it is used to increase the half peak time in switching impulse tests on inductors and to keep the wave form in line with the relevant standards.
