Resistive Reach Calculation of Distance Relay

Resistive Reach of Distance Relay Characteristics is defined by the fault resistance for which the distance relay characteristics is defined. In MHO type distance relay the major drawback is that resistive reach is defined by the impedance reach and line angle and hence it is not independently settable in the relay. However, it is independently … Read more Resistive Reach Calculation of Distance Relay

Single Line to Ground Fault Analysis

In earlier posts we discussed, Concept of Symmetrical Components and Calculation of Symmetrical Components. It is recommended to go through these topics before analyzing Single Line to Ground Fault.   You must read, Concept of Symmetrical Components and Calculation of Symmetrical Components   Let us consider a three phase system with earthed neutral as shown below.   Let us … Read more Single Line to Ground Fault Analysis
