Testing Commissioning SwitchGear

Description

Dear fellows,

This is the most comprehensive online training of MV switchgear. Here you will learn all thing about 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

• An overview of electrical transmission substation.

• Basic concepts about circuit breaker and Types of circuit breaker.

• Compartments of MV SWGR

• Current Transformer

• Voltage Transformer

• Earthing Switch

• Two-position Switch

• Protection Relay

• Operations of MV SWGR

• Mechanical interlocks of MV SWGR

• CB Trolley components

• CB Mechanism

• Why don't the distributor's switchgear have the same capacity ?

• The importance of having a dc ac voltage inside the distributor cells

• DC loop drawings

• AC loop drawings

• The main rules for reading the schema of current circuits and the reasons that lead to their explosion.

• Understand the general philosophy of closing, triping and interlock circuits.

• Upstream & downstream interlocks

• What is the working theory of anti-pumping relay and anti slam ?

• Importance of trip circuit supervision in the early detection of circuit breaker faults.

• The most important modifications in the schema before the distributor enters the service.

• The most important modifications before energize

• Introduction to 13.8KV ABB SwitchGear

• The Importance of Automatic Changeover Switching Equipment ACSE

• (Under Frequency  & Under Voltage)  Protection  Panel

• philosophy of High Impedance  BusBar Protection Panel
