Product Description

Product Description

sting of electrical insulation resistance characteristics of high voltage substations, power plants, remote power cables or buried cables. Brief description: test voltage: 0.5,1,2.5,5,10,20kV, resistance measurement range is wide from 0.01MΩ1999GΩ, accurate reading, high resolution, the short-circuit current of test power supply is typical value 10mA.

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.

Features

* With strong anti-electric field interference ability up to 2mA (50Hz), it is suitable for 500kV substation without dismantling wire to test insulation resistance of 500kV large-scale transformer.
* The short-circuit current of test power> 5mA, maximum up to 15mA. Be suitable for testing high capacity and high inductance.
* Wide resistance range from 0.5MΩ ~ 1999MΩ. With high-resolution, having accurate readings.
* Wide voltage range: 0.5kV, 1kV, 2.5kV, 5kV, 10kV, 20 kV, you can smoothly adjust voltage from 0V to the desired value.
* With timekeeping function, remind users to record, and analyze absorptance and polarization index of measured target.
