The induction withstand voltage test of transformers and mutual inductors is an important test to ensure that the quality of transformers meets national standards. The longitudinal insulation induction withstand voltage test for inter turn, inter layer, inter segment, and inter phase insulation of transformer windings is an important item in transformer insulation testing. Based on the particularity of longitudinal insulation testing, it is necessary to apply a frequency doubling power supply device to increase the test voltage of the insulation between windings, in order to achieve the purpose of withstand voltage testing.
It is designed and manufactured by our company based on on-site usage experience and customer feedback information to meet various customer needs. Its operation is simple, its performance is reliable, and it can better meet the needs of transformer and mutual inductance withstand voltage testing.
The instrument outputs a sine wave with low waveform distortion and a waveform distortion rate of less than 3%. The complete set of multi frequency induction voltage tester has a small size, good waveform, and stable output. The core component of the device, the variable frequency power supply, is controlled by a high-performance microprocessor and displays a full Chinese menu. It has the advantages of high automation, fast and reliable protection, and friendly human-machine interface. Please read these instructions carefully before use to avoid unnecessary damage to the test sample and testing device caused by misoperation.
Features
Multi frequency power supply device, outputting voltages of 50, 75, 100, 150, and 200Hz, used for AC induction withstand voltage testing of transformers, transformers, and other equipment.
