About this document
High vs Low Impedance Differential Protection by Sankalp Tiwari is a document available to read on EtoBox.
The document discusses high impedance and low impedance differential relay protection schemes. High impedance schemes introduce stabilizing resistors to increase the relay circuit impedance and prevent operation for spurious differential currents from things like CT errors. Low impedance schemes introduce slopes in the relay characteristics to provide stability without external resistors. High impedance schemes have higher stability against CT saturation from external faults, while low impedance schemes can
