Electrical actions

All the electrical actions such as power distribution, power transmission, power system protection are performed by using electrical panel only. Electrical panels are also known as MCCB panels or switchboards. It is a group of electrical equipment installed in a single enclosure to perform a specific function in a distribution system to protect a circuit breaker panel from short circuit & overload (using protective relays); to turn on or off small loads called motor starters or small generators connected to circuits and protect them from overloading and to disconnect larger amounts of equipment from a power supply within a building for example to separate incoming supply from other outgoing supplies in an electrical installation of a building or be the part of an external switchgear to receive electrical power from other sources outside the building and to provide the current to customers’ equipment or to the external public network outside a building of an installation.

Some activities carried out on current are tripping circuit breakers in response to faults on either an overhead line or a feeder and providing signals to inform the operator where in the electrical system the fault lies as well as control and monitor electric quantities like voltage and current on the protected feeders of power systems so as to assure adequate level of performance and safety of the system and protection of its components against abnormal conditions in order to distribute safe and economical electric power by utility lines over medium-voltage level in power transmission systems as well as high voltage inside buildings to power up the equipment and energize transmission lines of various types.
