Power Frequency Partial Discharge Testing Equipment /hipot tester
According to structure , the device can be divided into four type: single phase iron shell type,
single phase iron shell series type, single phase insulating clinger type and single phase insulating clinger series type. Usually single phase iron shell type is suitable for the occasions where voltage capacity is low and easy to carry , or the equipment is fixed and its voltage capacity is high but with low requirement for partial discharge . Single phase insulating clinger type is usually suitable for the occasions where the requirement of partial discharge is high, but low voltage and fixed. Single phase insulating clinger series type is mainly used for the occasions where the requirement of partial discharge is high,and high voltage,large capacity and easy to carry. All above four type can be select by user's requirement.
