HTDP-H VLF Hipot Test Set

t is designed and manufactured for electrical voltage 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformers and lines etc. all electrical main equipment withstand voltage test. Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test.

We know that when do power frequency withstand voltage test of large generators, cables etc., because of their insulating layer with large capacity, need large-capacity test transformer or resonant transformer. These devices, not only bulky, high cost, and very inconvenient. To solve this problem, power sector uses the 0.

1Hz ultra-low frequency HV generator test device, reduce the test frequency to reduce the capacity of the test power, thus greatly simplifying field testing difficulty. From home and abroad for many years theories and practices have proved that with 0.1Hz ultra-low frequency withstand voltage test replace power frequency withstand voltage test, not only have the same equivalence, and the volume of the device is greatly reduced, greatly reduced weight, theoretical capacity is about one five-hundredth of power frequency.
