Product Introduction

With the rapid development of China's power industry, preventive test of electrical equipment is an important link to ensure the safe operation and maintenance of power system. Insulation diagnosis is an important means to detect insulation defects or faults of electrical equipment. Insulation resistance measuring instrument is a special instrument to measure insulation resistance. The jjg662-89 insulation resistance meter (megohm), which was approved in May 1990, has been used as one of the mandatory instruments. At present, electrical equipment toward large capacity, high voltage, structure diversification and sealing the trend of development. Therefore, resistance measuring instrument(pointer) requires large capacity, strong anti-interference ability, diverse measurement indexes, accurate measurement results, simple and rapid measurement process, easy to carry and other characteristics.

Resistance measuring instrument manufactured by Wuhan UHV adopts ultra-thin tension-wire gauge head, multiple voltage levels output, large capacity, strong anti-interference, ac-dc dual purpose (C type), simple operation, and time raising function. It is an ideal instrument to measure insulation resistance of transformer, mutual inductor, generator, high voltage motor, power capacitor, power cable, lightning arrester and other insulation resistance.

Product nickname:Resistance measuring instrument, Insulation measuring instrument, high voltage Insulation resistance measuring instrument, Insulation characteristic measuring instrument, electrical resistance measuring instrument, electronic Insulation resistance measuring instrument, high voltage high voltage measuring instrument
