Product Description

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

1. Strong anti-interference ability: The anti-interference ability of the electric field reaches 2mA (50Hz). It is known to be suitable for measuring the insulation resistance parameters of 500,000-volt large-scale transformers without disconnecting the site at the 500,000-volt substation.
2. Large short-circuit current: typical short-circuit current is 10mA, suitable for testing of large capacity and large inductance
3. Wide resistance measurement range: The measurement range is from 0.01MΩ to 1999GΩ, with accurate readings and high resolution.
4. Wide range of high voltage output: 0.25kV, 0.5kV, 1kV, 2.5kV, 5kV, 10kV can be selected, and it can be smoothly adjusted from 0V to the required voltage
5. Sound and light reminder: It has a time-keeping function to remind the user to record and analyze the absorption ratio and polarization index of the measured object.
6. High quality: All key components are imported components to ensure accurate measurement accuracy
7, easy to use: the use of integrated chassis, small size, light weight, easy to carry
8. Exquisite appearance: using solid and abrasive materials to make the overall texture and service life of the instrument longer
