Partial Discharge-Free Power Frequency Withstand Voltage Test Set

Partial-discharge-free test transformers are essential testing equipment for the inspection and preventive testing of power equipment. Due to sulfur hexafluoride’s excellent insulating and arc-quenching properties, as well as its non-flammability, it has been widely adopted as a new insulating medium in power systems. Compared to oil-immersed partial discharge-free test transformers, the HMYDQW-30KVA/150KV ultra-lightweight gas-insulated partial discharge-free test transformer offers advantages such as compact size, light weight, no oil contamination, immunity to climatic changes, and minimal corona discharge. The voltage rating of a single unit can reach up to 300 kV.
