HVGM-5KV/ HVGM-10KV/ HVGM-15KV/ HVGM-20KV HV Digital Megohmmeter(New Model、Classic Model）

Ⅰ Introduction

For safety, before use the instrument must be well earthed. That’s because the measured target connects to high voltage power, and exists power frequency leakage. 
Once high voltage has started, do not use manual discharge method to check the instrument. After test, please wait the instrument completes automatic discharge and automatically returns to zero, then manual discharge can be operated. That is because electrical pulse caused by short-circuit discharge will damage the insulation life of the measured object; if the pulse fleeing into the instrument, will also damage the integrated circuit inside the instrument.
The instrument is designed for HV substations and power plants to test the characteristic of large HV transformer, electric machines and appliances, remote power cable or buried cable and other electrical insulation resistance in strong interference environment. It also can be widely used for testing characteristics of insulation resistance in other area.
