Brief Introduction

With the update and development of modern technology,it has higher requirements about reliability of power system and high-voltage equipment.Accidents or damage to electrical equipment are usually associated with insulation defect .Large capacity, high voltage, structure diversification and sealing put new and higher demand for electrical equipment .With the increasing use of large-capacity equipment, the insulation performance cannot be tested by ordinary megohm meter. 

Electric power test regulations require a series of insulation performance tests for a large number of electric power equipment such as cables, motors, generators, transformers, CTPT, high-voltage switches and arresters. Firstly need to make insulation resistance test .

When testing the insulation resistance of large capacity power equipment, the insulation resistance value is related to the pressure time. The longer the pressure time is, the higher the insulation resistance value is. This phenomenon is called insulation absorption.In order to understand the insulation performance of tested product, the absorption ratio and polarization index should be tested first, so as to provide safety guarantee for the next step of leakage, dielectric loss, partial discharge testing, etc. In accordance with electric power standardization procedures, our company specially launched the intelligent double-display insulation resistance tester with large capacity, high anti-interference and stable performance, conducted insulation, absorption ratio and polarization index tests for electric power equipment, and provided previous accurate judgment for insulation tests.

As the charging current directly affects the insulation value test of capacitive tested object with large-capacity, so large charging current is required, and the higher the charging capacity, the closer the absorption ratio test value is to actual value.The short-circuit current of this instrument is greater than 3.3ma, which overcomes the disadvantages such as small short circuit current of common megohm meter, inaccurate test and easy interference.This instrument adopts timely voltage and current sampling for division calculation, so the resistance value calculated by ohm theorem is accurate even if the voltage changes during testing.This instrument adopts principle of combining the digital pointer , output multi-block voltage, which is convenient for new and old customers.Convenient to carry and easy to operate;It is equipped with a large-capacity rechargeable lithium battery, which can be used for both ac and dc,also with undervoltage warning and over-charge protection.This instrument can automatically display current time, and save 200 sets historical test data and time, which provides great convenience for test person .This instrument is a new kind of intelligent instrument, which is the best choice insulation testing .
