Connection to local utility
Connection to local utility
(OP)
Dear all:
We are installing a generating center to supply loads to an industrial Plant. The generating center is gas internal combustion motors based, totaling 21 MW. Generators terminal voltage is 4.16 kV, there are installed step up transformers to bring voltage to 34.5 kV.
Our 4.16 and 34.5 kV switchgears have circuit breakers and up to date microprocessor based protective relays. Motor and generators are well protected complying all European directives.
Our client wants to connect the local generation and the load to the local utility using a standard 34.5 kV recloser (with reclosing option disabled), our Plant control shall command tripping and closing of the recloser.
I would like to hear comments about this recloser application.
Thanks in anticipation

RE: Connection to local utility
We use reclosers for utility tie connections where the fault currents allow. But normally at 34.5 kV we generally end up with a circuit breaker.
