Protection of distributed power supply connection to power system,
The relay is smaller, and the protection unit is more enriched.
Waste heat generation system improve the comprehensive energy efficiency and the use of natural,
Energy of wind power generation, the spread of power is becoming more and more popular K3GN-NDC PDF.
This relay is used to detect the internal fault of the user in the distributed power supply,
Power line accident of distributed power supply and relay protection system K3GN-NDC
The relay can be meet in Japan (system connected instant points specified in the standard model),
Function, can be through more than 20 kinds of products to establish the best protection system K3GN-NDC PDF.
Can also correspond to the generator and the electric side / internal tributaries.
Unit with 2 relay elements.
In each unit, the variable action time circuit is hidden, so that the coordination design is more convenient K3GN-NDC PDF.
