Ground Distance Relays - Understanding the Various Methods of Residual Compensation, Setting the Resistive Reach of Polygon Characteristics, and Ways of Modeling and Testing the Relay

The correct operation of ground distance relays is highly dependent on the correct application of the residual or zero-sequence compensation factor. But what are these factors. Various relays vendors have different forms of naming, defining and applying these factors and this confuses relay application engineers. More
