Insulating Oil Breakdown Voltage Tester

An Insulating Oil Breakdown Voltage Tester, also known as a dielectric strength tester or transformer oil tester, is a specialized instrument used to measure the breakdown voltage of insulating oils. Insulating oils, such as transformer oils, are crucial for the effective insulation and cooling of electrical equipment like transformers, switches, and circuit breakers.

The breakdown voltage of insulating oil refers to the voltage at which the oil loses its insulating properties and breaks down, allowing electrical current to pass through. This breakdown can occur due to various factors such as moisture, contaminants, or degradation of the oil over time.

The Insulating Oil Breakdown Voltage Tester applies a gradually increasing voltage to a sample of insulating oil until breakdown occurs. By measuring the voltage at which breakdown happens, the tester can assess the quality and effectiveness of the insulating oil. This information is vital for ensuring the reliability and safety of electrical equipment, as well as for diagnosing potential issues or degradation in the insulation system.
