Clarification of multi-point grounding troubles using an oscilloscope! A device that can test under conditions almost identical to actual accidents.
The device is designed for control and protection simulation of power systems (transmission lines, substations, and power plants). It allows testing of relay devices targeting accidents (faults) involving complex transient phenomena under conditions nearly identical to actual accidents (faults). As it is a custom-made product produced on a made-to-order basis, please feel free to consult us when you need it. 【Features】 ■ Response testing for transmission line protection, on-site protection, transformer protection, etc. ■ PCM carrier relay, distance relay, digital line selection testing ■ Clarification of multi-point ground fault issues using an oscilloscope ■ Operation of transmission line ■ Custom-made product produced on a made-to-order basis *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Production Use Case】 ■Overview: A simulated transmission line device that mimics the transmission line's impedance, allowing for variable adjustments to generate single-phase ground faults, two-phase ground faults, two-phase short circuits, and three-phase short circuits, for testing the operation of protective relay panels. ■Functions - Generation of short circuits in the transmission line circuit (two-phase short circuit, three-phase short circuit) including line reactors (capacitance). - Generation of ground faults in the transmission line circuit (two-phase ground fault, three-phase ground fault) including short circuit reactors (capacitance). The neutral grounding method can switch between resistance grounding and reactor grounding. *For more details, please refer to the PDF document or feel free to contact us.
