The following protection relays are used to detect grid disturbances, its severity and isolate the inplant system from the grid.
The 110 and 220 kV lines of the main grid are protected by means of two primary protection schemes (two distance relays or a distance and a differential line relay) or a primary protection relay (distance
Originally presented at the 33rd Annual Western Protective Relay Conference, October 2006
This article covers various types of protective relays, such as overcurrent, directional, and differential relays, highlighting their operating characteristics and applications
For more difficult relaying applications, such as EHV lines using series capacitors in the line, some companies always use two sets of solid-state relays
