What is the procedure for BDV testing?

The procedure for BDV testing involves several key steps to ensure accurate measurement of the breakdown voltage of insulating oils. First, prepare the sample by filtering it to remove any impurities or particulates. Next, fill the testing cell with the oil sample, ensuring there are no air bubbles. Then, connect the testing apparatus and set the required voltage increment, typically starting at a low value and increasing until the breakdown occurs. Monitor the voltage closely as it rises, and when the oil breaks down, record the voltage at which this occurs. It’s essential to conduct the test according to ASTM D1816 or IEC 60156 standards for consistency and reliability. Proper calibration of the equipment is also crucial before testing. Using reputable bdv tester manufacturers ensures that the equipment adheres to industry standards for performance and accuracy.
