Summary

This TB is intended to assist the relay application engineer in the correct selection and application of busbar protection. It provides relevant information about their performance, operation, testing, and maintenance. Two main designs used for HV busbar protection today are high impedance and low impedance differential protection systems. Features of modern low impedance differential protection are described in details.
