Shunt trips are devices used for the remote
instantaneous opening of the air circuit
breaker. They are generally controlled trough
an N/O type contact. The actual offer of
shunt trips proposes two supply voltages
(110 V and 220 V), both compatibles with AC
and DC currents. The shunt trips are already
equipped with a special fast connector, to
be directly inserted into auxiliary contacts
block. An auxiliary contact is connected in
series with the coil, cutting off its power
supply when the main poles are open.

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
