Overview
With the rapid development of China's power industry,
electrical equipment preventive experiment is an important part in
protecting the safety operation of power system and maintenance.
Insulation diagnosis is an important method to detect insulation
defects or failure. Pointer insulation resistance tester is the special
instrument to measure insulation resistance. JJG662-89
"insulation resistance meter (megger)" approved in May 1990
requires that insulation resistance meter is one of compulsory
verification instruments. Nowadays the development trend of
electrical equipment (such as transformers, generators, etc.) is that
high capacity, high voltage, diversified structure and better seal. So
insulation resistance meter (pointer) itself must have the
characteristics such as large capacity, strong anti-interference ability,
diversified measurement indexes, accurate measurement results,
easy and fast measurement process, easy to carry and so on. The
instrument produced by our company is equipped with ultra-thin
taut suspension meter. It is an ideal tester to measure insulation
resistance of these equipments such as transformer, instrument
transformer, generator, HV motor, power capacitors, power cables,
arrester, etc.
