what is lv switch gear
types of lv switchgear
A mains transformer or backup generator distributes power to the switchgear by conductors or electrical connectors to an input fuse box or appliance, often an Air Circuit Breaker (ACB) or a Moulded Case Circuit Breaker (MCCB). Power is routed throughout the switchgear through inbuilt copper rods that supply lower-rated fuses, again ACBs or MCCBs, on the transmitter .Low-voltage switchgear is typically used to feed low-voltage motor control centers (LV-MCC), low-voltage switchboards and other branch and feeder circuits. It is used to supply electricity for critical power and critical process applications such as those found in heavy industry, manufacturing, mining and metals, petrochemical, pulp and paper .

Low-voltage switchgear, designed to distribute three-phase power, is a critical part of an electrical power system. Erik Hurd, Senior Power System Experience. In addition LV switchrooms often also house other related equipment – marshalling panels, UPS systems, control panels etc.. This article gives some design guidance for the correct sizing of these rooms. Switchboards. In laying out the LV switchroom, actual switchboard dimensions should be used. Typical switchboard dimensions would be:The Role of Low Voltage Switchgear in an Electrical System. In LV systems, we use LV switchgear to measure, control, and regulate electrical quantities such as voltage current, and protect the system from faults. The reliability of the low voltage system depends a lot on LV switchgear. The main functions of LV switchgear are: Isolation
