Dielectric oil is often used in transformers, capacitors, high voltage switches and circuit breakers as an insulator and a heatsink. It is important to keep the oil free from impurities to ensure reliable operation of the electrical component. Accumulation of acids, moisture or organic debris on the dielectric oil can lower the breakdown voltage, allowing current to flow through it. This can cause serious problems to the electrical component and may lead to eventual failure.
To help you assess the condition of dielectric oil in electrical components, consider getting an Oil Dielectric Test Set. This device allows you to determine if the breakdown voltage is still within the acceptable range or if the oil needs replacement. Below are some of the trusted devices when it comes to oil dielectric testing.
The OTS-60SX is a semiautomatic device that lets you set the voltage rise rates depending on the test standard you want to conduct. It is portable and can be powered using a wide range of mains supply. The device also has a pause function so you can carry out a withstand test.
