It is essentially the first electrical panel that connects the electricity and power to the site.
E12 PREVENTATIVE MAINTENANCE TECHNICAL DATA SCHEDULES Switchboard - Main ELECTRICAL Activity Type Of Service Last Amendment Date:18/02/15 A B C D E 1 GENERAL A switchboard may include a metering or control compartment separated from the power distribution conductors. When these are required for electrical power distribution an electrical switchboard solution from CUBIC is the ideal choice. In precise, An electrical switchboard gets power supply from a power generator or any other major power source. They can be separated into two major group of Analog Power Meter and Digital Power Meter shown here.Power Meter has become more and more popular as the price has decreased over the years.Backup power comes in many form and many levels.
to the Sub Switchboard which is also known as the The main Low Voltage Switch that is used to disconnect the electricity. A switchboard may have incoming bus bars or bus duct for the source connection, and also for large circuits fed from the board. An electrical switchboard is a single large panel or can be a combination of electrical panels on which switches and other power control equipment are mounted. We also cover complete turnkey services such as servicing, rectification, repair or renewal of instruments, switchboard circuit breakers and control systems as well as provide manpower to commission the control systems. "NEMA Standards Publication 2-2011 Deadfront Distribution Switchboards," Rosslyn, VA: National Electrical Manufacturers Association, 2011. A main structure will contain the main disconnects or main lugs and will often contain utility and/or customer metering equipment and surge protection. It is used for receiving, measuring and distribution of electrical energy and protects the network from overload, short-circuit and current leak. The Main Switchboard may also be known as the Switchgear Panel and Main Distribution board in other countries than in Singapore. They fulfill requirements of the most energy-intensive sites, and of sites with harshest operating conditions. The role of a switchboard is to divide the main current provided to the switchboard into smaller currents for further distribution and to provide switching, current protection, and metering for these various currents. Each electric panel contains switches that redirect electricity. It divides the main current supplied to it into several smaller chunks and distributes it to the devices.
Main LV switchrooms will typically contain free standing switchboards and Motor Control Centres (MCC), along with auxiliary equipment required for the room to function (bus ducts & cable containment, distribution boards, lighting, small power, air-conditioning equipment, fire fighting, etc. The connection and the disconnection of the electricity to the site can be done via a Circuit Breaker or a Switch Disconnector.The second function of the power distribution of the switchboard is to distribute power to each area of the site. It is used for receiving, measuring and distribution of electrical energy and protects the network from overload, short-circuit and current leak.
An electric switchboard is a device that directs electricity from one or more sources of supply to several smaller regions of usage.
They perform the added Protection Function discussed below as well. - Main switchboard – A switchboard which is directly supplied by the main source of electrical power and is intended to distribute electrical energy to the ship service, (SOLAS).
