Description：WF-ZJB gap transformer neutral point grounding protection devices dedicated to 110KV, 220KV, 330KV, 500KV power transformer neutral point, in order to achieve neutral point grounded or ungrounded two different operation modes designed to avoid transformer
Description：WF-B transformer neutral grounding resistor cabinet to reduce over-voltage grid, improve network security, reliability, with good results. 6 ~ 35kV cable for power supply system grounded capacitor current larger system.
Description：WF-F-type generator neutral point resistor cabinet is designed for high-power plant generator neutral grounding resistor sets of devices. Generator voltage level mainly 6kv to 20kv. When the stator point grounding occurs when the limit ground current in a
Description：WF-PXH bias Petersen Coil Automatic Compensation sets of devices in real-time monitoring of single phase grid current size, then the Petersen coil reactance value is large, equivalent ungrounded system. In the event of single-phase ground, in a very short
Description：Frequency sensitive rheostat is folded into the core of cast iron sheet or plate, and then put out of the reactor phase windings, the rotor winding is connected to the circuit, the winding and the core loss of electrical resistance determined by the imped
