Transformer capacity tester is a common high voltage electrical testing equipment, mainly used to measure the DC resistance of power transformers. Transformer DC resistance tester is a common high voltage electrical testing equipment, mainly used to measure the DC resistance of power transformers. It has also been widely used in power industry, but many people do not know about its measurement and discharge work. For transformer DC resistance tester measurement, after connecting the test line, turn off the power switch, turn on the power indicator, press the "start and stop button".

Select the range of resistance range according to the measured value, press the range switch, the range indicator will light up, the stable value displayed on the LCD screen is the measured resistance value. When reading the values, note the units in the selected range and measure large inductance samples such as power transformers and other test circuits other than coils. To avoid electromagnetic interference, it is not necessary to measure short circuits. Transformer DC resistance tester discharge, test should be directly cut off the main power supply.

If the power supply should not be cut off immediately after operation in a perception test, the instrument should have a continuous discharge process, usually at least 20 seconds. Otherwise the inductance of the back potential will be a crisis of personal safety, in the power industry has also been widely used.
