The dielectric strength of a transformer is measured using the transformer bdv test procedure, which involves applying a high voltage to the insulating oil until breakdown occurs. This process typically requires a dielectric strength tester or a breakdown voltage tester, which conducts the test according to established standards. During the test, the oil sample is placed between two electrodes, and the voltage is gradually increased until a spark or breakdown occurs. The breakdown voltage is recorded, indicating the dielectric strength of the transformer oil. This measurement is critical as it helps assess the insulation quality and overall reliability of the transformer, ensuring safe and efficient operation in an industrial setting. Globecore offers reliable equipment for conducting these dielectric strength tests effectively.
