Description
Series of High-voltage Tester of AC & DC (Non-partial Discharge) for Light Oil-immersed Transformer
Technical parameter:
HRYDJ（W）series are made of high-quality materials, which contribute to its low losses, small volume, little weight, compact construction and convenience. It is widely used in power & electric system, research institutes, and large mining factories to do the tests of AC & DC withstand capability and insulating materials' characteristic for any kinds of high-low voltage power equipments, power cables, generator, etc. Testing transformer is divided into tow kinds of voltage: single-stage and cascade. Special order is also available.
