DC hipot tester EPTC-M+

AC

AC hipot testing is the effective and direct way to test insulation strength for electric equipment. It check dangerous flaws and make sure electric equipment continuous working. It typically used to test insulation strength for all kinds of electrical equipment, components like capacitors, insulation materials. EPTC-M Series AC/DC Hipot Tester is suitable for hipot dielectric withstand test on various power electric products, units, insulating material and etc. The working principle is: by adjusting the output voltage of the auto-regulator, the working voltage adjustment within the rated voltage range of the rated pressure device of the power frequency withstand voltage test device is realized. At the same time, the control box is equipped with a high-voltage output voltmeter, a low-voltage input current meter and an overcurrent protection circuit. The test voltage value can be easily read and can be reliably protected. The principle is simple, compact and reliable, and it is an ideal equipment for hipot test. The controller should be equipped with AC/DC HV source to boost. There are three types of testing transformers for optional. 1. Oil-immersed: large capacity, cheap, convenient maintenance, mainstream products. 2. Dry type: light weight, light volume, can run backward, price expensive. 3. Gas inflatable type: interrupter resistance, and light weight. 4.Series type high voltage testing transformer: small volume, low voltage, light weight, easy to transport and install.
