electrical voltage

Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of.

Medium voltage is a class of nominal system voltages that is higher than 1,000 V and lower than 100 kV. It is commonly used for subtransmission, primary distribution, and industrial motors. The range of medium voltage may vary from 600 V to 69 kV depending on the equipment ratings and standards.

An increasing amount of low carbon technologies (LCT) such as solar photovoltaic, wind turbines and electric vehicles are being connected at medium and low voltage levels to electric power networks.

electrical current

Electric current is the movement of electric charge carriers such as electrons having negative charge, protons having positive charge, ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles) ². The intensity of electric current is usually measured in amperes.

Electric current is used in many practical applications such as charging batteries, operating household appliances like bread toasters, baking ovens, televisions and mobile phones¹. It also plays an important role in industries, transportation and communication.

electrical switchboards

An electrical switchboard is a piece of equipment that distributes electric power from one or more sources of supply to several smaller load circuits. It is an assembly of one or more panels, each of which contains switching devices for the protection and control of circuits fed from the switchboard². 

Switchboards are used to safely distribute electricity throughout commercial and industrial facilities. A switchboard is a component of an electrical distribution system which divides an electrical power feed into branch circuits while providing a protective circuit breaker or fuse for each circuit in a common enclosure
