3.1. Pole Mounted Substations
These substations are mainly used to supply isolated rural consumers from MV overhead line distribution systems. In this type of substation, most often, the MV transformer protection is provided by fuses. Lightning arresters are provided, however, to protect the transformer and consumers as shown in Figure 1. As previously noted the location of the substation must allow easy access, not only for personnel but for equipment handling (raising the transformer for example) and the man?uvring of heavy vehicles [3,5].
