Abstract Insulating Oil Dielectric Strength Tester has wide application for High voltage. There are many devices need to calibrate. The risk of the calibration process is large, and it is easy to cause personal injury and damage to the equipment caused by misuse.Domestic lack of specialized equipment. A special device is designed to guarantee the calibration process by the design of initiative breakdown module, protection module, sample processing module and to further strengthen the accuracy of the calibration.
