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
Busbar arrangement
Arcing Compartment
CB Compartment
Cable Compartment
VT Compartment
Control & Protection Compartment
Control Circuit
Mimic
Protection & Control Relay ( BCPU)
Operations of MV SWGR
Mechanical interlocks of MV SWGR
CB Trolley components
CB Mechanism
Closing & Tripping Spring
CB & Isolator Aux Contacts
Tripping & Closing coils
GE SECO gear 3D operations
Eaton FMX switchgear 3D operations
Siemens NXAIR 3D operations
