1ELECTRICAL PROTECTION SYSTEM
Executive Summary
The substation's main purpose is to obtain power from the high voltage source that is from
the power stations. In this scenario, the Berserker Substation is focussed. The redundancy is
beneficial for restricting power interruption and regulates normal flow of current whereas the
protection relay is beneficial for securing the feeder and reducing the fault. The Earth-fault
protection along with relay coordination for the earth-fault relay has been explained
elaborately.

1. Introduction
The substation’s main purpose is to obtain power from the high voltage source
that is from the power stations. In this scenario, the Berserker Substation is focussed.
This report will highlight the equipment, design associated and also the
redundancy and the protection relay will be showcased.
2. Objective
The Berserker Substation is constructed along with the equipment incorporated
keeping in mind the following advantages it can provide-
 The primary objective of the substation is to acquire the power which flows at
a high voltage from the stations where power is generated [2].
 Gas Insulated Switchgear (GIS) technology reduces substation
accommodation to seventy per cent.
 Switchgear which involves the circuit breakers and these circuit breakers are
responsible for intervening the short-circuit current generated from the power
stations.
 Surge arresters to safeguard the switchgear from over voltages happened due
to lighting thus regulates the normal current flow [1].
 Substation automation to protect, secure and control the electrical components.
 The construction work must be comparatively simpler and cheaper and must
be flexible for an extension if required.
