Description
Dear fellows,

This is the most comprehensive online training of MV switchgear. Here you will learn with 3D simulation of several MV Switchgears.

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.

we will go through the following topics

Compartments of MV SWGR

Current Transformer

Voltage Transformer

Earthing Switch

Two-position Switch
