An insulating oil dielectric strength tester measures the breakdown voltage of transformer oils to assess their insulation quality and safety. This test prevents electrical failures by ensuring the oil can withstand high voltage stress. Chinese manufacturers like Wrindu supply advanced, reliable testers ideal for OEM, wholesale, and customized applications across power industries.
How Does an Insulating Oil Dielectric Strength Tester Work?
The tester applies increasing high voltage to an oil sample until electrical breakdown occurs, indicating the oil’s dielectric strength. The breakdown voltage is recorded, revealing the insulating performance. Advanced Chinese factories such as Wrindu develop precise testers compliant with IEC and CE standards, offering automatic test features and data accuracy.
