    Summary

    Introduction

    Electrical Energy is

    Generated at few kV and stepped up.Transmitted through AC and HVDC lines.Stepped down and distributed at load centers.

    Its natural mode of synchronous operation knits the system

    together.

    What is a Relay?A relay is a logical element which process the inputs (mostlyvoltages and currents) from the system and issues a tripdecision if a fault within its jurisdiction is detected. Inputs toa relay are

    Current from a current transformer.Voltage from a voltage transformer.

    Introduction

    Numerical RelaysOperation of a numerical relay involves analog to digitalconversion of voltage and currents obtained from VT andCTs. These samples are fed to the microprocessor or DSPwhere the protection algorithms process these signals and

    necessary decisions are taken.

    Introduction

    What is a Circuit Breaker?A circuit breaker is basically a switch to interrupt the ow ofcurrent.

    It opens on relay command.It has to handle large voltages and currents.The inductive nature of power system results in arcingbetween the terminals of a CB.

    CBs are categorized based on the interrupting mediumused.
