How is a Megger BDV test performed?

The Megger BDV test is performed using a specific type of tester designed for measuring the breakdown voltage of insulating liquids, such as industrial oils. To carry out the test, you first ensure the instrument is calibrated and in good working order. Next, you prepare the sample of the insulating liquid by placing it in a clean testing cell or cup. The tester applies a gradually increasing voltage to the sample through electrodes immersed in the liquid. As the voltage increases, the tester monitors the electric current, and when the current suddenly increases, indicating breakdown, the tester records the voltage at that moment. This breakdown voltage, or BDV, is critical for assessing the electrical insulating properties of the oil. After the test, it’s essential to clean the equipment to prepare for future use. For the latest information regarding the bdv tester price, it can vary based on the model and features, so checking directly with Globecore or their distributors for pricing details is recommended.
