What is the difference between VLF and hipot ?
What is the difference between VLF and hipot?
VLF Testing is a AC hipot tester that perform the withstand and diagnostic testing for test object at very low frequency 0.1 Hz to 0.01 Hz . It is applied for HV/MV cable, motor and generator and other high capacitive loads.
Vacuum switch vacuum degree tester
Vacuum switch vacuum degree tester utilizes an innovative excitation coil and employs the magnetron discharge method to evaluate the vacuum degree of the arc extinguishing chamber without requiring disassembly.
What is the transformer temperature rising test ?
When the temperature of transformer accessories exceeds its allowable range for a long time, even the transformer oil temperature is 10℃ higher than normal or the temperature is still rising, the insulation of transformer will be easily damaged and broken down by high voltage,causing failure or accidents . In order to ensure the normal work and service life-span of transformer, it is very important to evaluate the transformer heat up. Let’s discuss the transformer testing for temperature rising in the article .
