One machine one switch and one-level distribution box

Typical equipment for this system arrangement is a single unit substation consisting of a fused primary switch, a transformer of sufficient size to supply the loads, and a low-voltage switchboard. This arrangement is shown in Radial System with Primary Selectivity., the second level contains a large three-phase circuit breaker, and the third level contains a single-phase circuit breaker. The primary distribution box refers to the main distribution box, typically located in the distribution room. Let's make an example for clarity: A newly constructed residential area introduces a 10kV power line to a substation. From the transformer's low-voltage side (0. This electrical. The engineering draw...
