Main power distribution equipment are transformers, circuit breakers, switches, protection relays and uninterruptible power supply are the backbone in all electric power distribution network. Installing the correct power transformer rating is important as it entails the vector group, transformation ratio, tap changer and impedance percentage. Circuit breakers are the primary equipment to open when a fault arises. The types of circuit breakers are named according to its arc extinguishing medium namely, oil, air, gas and vacuum.
Protection relays are the eyes and ears of the electrical distribution system. If there is any abnormally it will operate and prevent damage to the equipment and injuries to the operators. State of the art intelligent numerical relays are incorporated in all electrical circuits to ensure safe and secured operations. In the event of an outage uninterruptible power supply systems are installed to ensure that the critical and essential loads are not affected by the outage.
