Function of relays in high-voltage distribution boxes
High voltage relays are electromechanical devices used to switch high voltage (> 1kV) signals. Thus, the disadvantage to other parts of the network due to undervoltage will be reduced to a minimum. The fast operation of the protection also reduc-es post-fault load peaks which, in combination with the voltage dip, increase the risk of the disturbance spreading into healthy parts of the. Inside these boxes, you've got some key parts like circuit breakers, transformers, and protective relays.
