Dielectric loss measurement is a basic method in insulation test and 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. Measurement on dielectric loss of transformer,
mutual inductor, reactor, capacitor, bushing and arrester is the most basic method to
test their insulation property. fully-automatic anti-interference dielectric loss tester
breaks through the traditional bridge testing method and adopts variable frequency
power technology, single chip and modernized electrical 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 45Hz and 55Hz pure sine wave and automatically increase the voltage to a
maximum value 10 KV. It can filter 50Hz interference automatically, and it is applicable
to the site test of substation and other places 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.
