The transformer is referred to as the measuring and protection current transformer and voltage transformer collectively. It is the basic equipment that helps achieve electrical primary and secondary system interconnections. The conversion of high voltage and high current in the primary system into low voltage and low current to be used in measuring instruments, relay protection, and automatic devices in the secondary system is performed by means of transformers. Besides being the element connecting the primary system to the secondary system in the power system, it also plays a role as an element of isolation.
