What is a 10kV shared busbar

In , a busbar (also bus bar) is a metallic strip or bar, typically housed inside,, and for local high current power distribution, transmission, or switching substations. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in. They are generally uninsulated, and have sufficient stiffness to be s.

How to switch over in case of a 10kV busbar PT failure

The switching is done by using two auxiliary contacts on the busbar disconnectors. In case of failure of either of the transformers, busbars, cables or their associated switchgear, a changeover option between the two will be at hand to keep the loads up and running. At 1 ½ breakers system arrangements a 2-zone protection must be used as in the Figure 2. Metal-Clad Switchgear is the premium choice for high-reliability requirements. i mean if pt is not in operation position you can not close the circuit breaker. is it necessary?
