Now power substation comes in a box

Here at Bangalore, I found package substation beside road which primarily is used to reduce the size of a substation in a cubical of rated capacity of 750 kVA, which steps down 11kV to 433V. The important point that is eye caching here is that this cubical contains four circuit breaker, five mccb, instrumentation system a copper wound transformer and two grounding points. This transformer is specially manufacted to this design so as to reduce the size upto one third, manufactured by Kotsons company. The transformer is hermatically sealed without conservator, breather. The oil tank is vaccumized to reduced the space for conservator.
