A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase. To make the transformer connections compatible with three-phase supplies we need to connect them together in a particular way to form a .

Distribution transformer protected with spark gap according to the SFS 2646 standard [6]. III. SERIES IMPEDANCE BASED PROTECTION n alternative to a special transformer design is to intro In electrical power system the range of current and voltage is very high and so it is not possible to measure these values directly by any meter of reasonable size and construction.. So there is a need to step down these voltages or currents to such a value so that it can be easily measured..
