Introduction
The measurement of dielectric loss is a fundamental method in the insulation test and effectively detects the moisture, deterioration and partial defects of the insulation of electrical devices. This method is widely used in power generation, distribution and connection facilities and preventive tests. Dielectric loss measurements in devices such as transformers, inductors, reactors, capacitors are the most basic method for testing insulation properties.
This device is characterized by powerful interference prevention capability, high test speed, high precision, automatic digitization and easy operation.
With high power switching power supply, it can produce a pure sine wave at 45 Hz and 55 Hz frequencies and automatically increase the voltage up to 10 kV. It can be used in field tests of the substation and other places where the electromagnetic interference is high by filtering the 50Hz noise automatically.
