Anti-Interference Dielectric Loss Tester

Product Description1.Introduction:
Dielectric loss measurement is a basic method in insulation testand effectively detect damp, degradation and partial defect of insulation of electrical equipment. This method is widely used in electric manufacturing, electric equipment installation, connection and preventive test. Measurementon dielectric loss of transformer, mutual inductor, reactor, capacitor, bushing and arrester is the most basic method to test their insulation property.This high accuracy fully-automatic anti-interference dielectricloss tester breaks through the traditional bridge testing method and adopts variable frequencypower technology, single chipand modernizedelectrical technology to carry out automatic frequency shift, analog-to-digital conversion and data computing. It features strong anti-interference capacity, high test speed, high precision, automatic digitization and easy operation. It adopts high-power switching power supply, which outputs 45Hzand 55Hzpure sine wave and automatically increase the voltage to a maximum value 10 KV. It can filter 50Hz interference automatically, and it isapplicable to the site test of substation and otherplaces with large electromagnetic interference. This methods is extensively applied in dielectric loss measurement of transformer, mutual inductor, reactor, bushing, capacitor, arrester and others equipments in power industry.2.Testable parameters:
