Product Introduction & Features:
It is mainly used for testing frequency voltage insulation level of
various insulation materials, insulation structure and electrical
products, also as partial discharge frequency testing power supply
for testing object such as transformer, mutual inductor and
lightning arresters. It widely used in electrical manufacturing,
power operation departments, research institutes and
universities.HZJF System 10kVA/100kV composition.

Hezhong control Unit and PD-free testing transformer are
controlling and voltage boosting for test object which boosted to
the rated voltage.
Partial discharge detector is detecting and displaying partial
discharge capacity.
Isolation filter is device of anti-interference caused by power
supply.
Coupling Capacitor is transmitting partial discharge signal to
partial discharge detector.
