SwitchGear... continue from yesterday... Today i will give a brief explanation about the switch gear..
What is Switchgear?
Switchgear is a general term of covering switching devices and their combination with associated control, measuring, protective and regulating equipment.
3 terms that actually describe the function of the switchgear :-
- Control
- Measure &
- Protect
* The term switching device is a device that assigned to make a break the current in one or more electrical acts*
The very earliest switchgear central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levels and voltages rapidly escalated, making open manually-operated switches too dangerous to use for anything other than isolation of a de-energized circuit. By the early 20th century, a switchgear line-up would be a metal-enclosed structure with electricity-operated switching elements, using oil circuit-breakers. Today, oil-filled equipment has largely replaced by air-blast, vacuum, or SF6 equipment, allowing large currents and power levels to be safely controlled by automatic equipment incorporating digital controls, protection, metering and communications.

Industrial Switchgear
So, switchgear could be conclude as a very important parameters to determine the efficiency of the production in an industrial organisations. Almost all of the production factories, small or big, depends on the switchgear for their running process. This is to ensure the production flows is smooth and secure even though there are failure occurrence at some states.
