The transformer compartmentcontains a sealed type oilimmersed step down trans -former of the low loss type withaluminium windings in accor -dance with SABS 780 and isnormally supplied with an oillevel indicator and an off circuittap switch. These transformerscan be supplied on request with

dual inputs, for example, tooperate from either 11 000 V or6600 V medium voltage systems. The LV compartment containscircuit breakers, HRC fuses,metering and instruments tospecification.

Miniature substations are norm-ally available in type A or type Bconfigurations dependent ont h e s p e c i f i c a t i o n . The units are factory assem-bled bled and tested anddespatched as complete unitsand are suitable for installationin public areas , such as onresidential pavements, nearshopping complexes and inindustrial parks.
