Product Introduction

Dielectric loss measurement is a very basic method in insulation test, which can effectively find out the whole damp deterioration and local defects of insulation of electrical equipment.It is widely used in electrical manufacturing, electrical equipment installation, handover and preventive test.The measurement of dielectric loss of transformer, mutual inductor, reactor, capacitor, bushing and lightning arrester is the most basic method to measure its insulation performance.The dielectric loss tester has broken through the traditional bridge measurement method, adopting frequency conversion power supply technology, using single chip microcomputer and modern electronic technology to carry out automatic frequency conversion, mode/number conversion and data operation.Strong anti-interference ability, fast test speed, high precision, automatic digitization, easy operation;Power supply adopts high-power switching power supply, output 45Hz and 55Hz pure sinusoidal wave, automatically pressurize, can provide up to 10 kv voltage;Automatic filter 50Hz interference, suitable for substation and other electromagnetic interference large field test.Widely used in the power industry transformer, transformer, casing, capacitor, lightning arrester and other equipment dielectric loss measurement.

Product names:Dielectric loss tester, anti-interference dielectric loss tester, automatic dielectric loss tester, dissimilar frequency dielectric loss tester, dissimilar frequency dielectric loss tester, anti-interference dielectric loss tester, automatic dielectric loss tester
