WJY-3 insulation oil breakdown voltage tester

WJY-3Insulation oil breakdown voltage testerCompliant with GB/T507 and DL/T429.9 standards, used to test the degree of physical contamination of insulating oil by water and other suspended substances. The measurement method is to place the test oil in the equipment and subject it to an alternating electric field that uniformly boosts the voltage at a certain speed until the oil is broken down. It can be widely applied in industries such as power, petroleum, and chemical.

Insulation oil breakdown voltage tester

Instrument Features

1. Adopting dual CPU microcomputer control.

2. A series of operations such as boosting, zeroing, stirring, displaying, calculating, and printing are automatically completed.

3. Equipped with overvoltage, overcurrent, and automatic zero return protection devices, it is safe and reliable.

4. Adopting an automatic sine wave generation device and a stepless voltage regulation method to increase the pressure, the test voltage is stable and reliable.
