Clarification of multi-point grounding troubles using an oscilloscope! A device that can conduct tests under conditions almost identical to actual accidents.
This device performs control and protection simulation for power systems (transmission lines, substations, and power plants). It allows testing of relay devices targeting accidents (faults) involving complex transient phenomena under conditions almost 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 placing an order. 【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 oscilloscopes ■ Operation of transmission lines ■ Custom-made products produced on a made-to-order basis *For more details, please refer to the PDF materials 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, and to conduct operational verification tests of protection relay panels. ■Functions - Generation of short circuits in the transmission line circuit including line reactors (capacitance) (two-phase short circuits, three-phase short circuits) - Generation of ground faults in the transmission line circuit including short circuit reactors (capacitance) (two-phase ground faults, three-phase ground faults) The neutral point grounding method can be switched between resistance grounding and reactor grounding. *For more details, please refer to the PDF document or feel free to contact us.
