Detection impedance (input unit)
Partial Discharge PD Test - Fivestar HV Testing Equipment Co., Ltd. (FSHV)
Detection impedance is the importance unit to detect the discharge information from discharge testing loop, also known as input unit.
There are two kinds of detection impedance, ordinary detection impedance and capacitive divider detection impedance, capacitive divider one can test voltage and zero mark position without connecting to external divider.
