Load Interrupter Switch for Medium Voltage Generators
Load Interrupter Switch for Medium Voltage Generators
(OP)
I have 4 medium voltage generators (13.8KV) connected to a paralleling switchgear. The generator's manufacturer is recommending to use a load interrupter switch, SF6 type, rather than a simple safety disconnect switch on each generator. I know that the circuit breakers in the paralleling switchgear provides protection to the generators, i.e. excitacion loss, etc. What is the purpose of using this load interrupter? Thanks

If this is a packaged genset, sometimes they have integrated electronic protection relays which might be wired to open the interrupter. If so, you would need to provide an alternative interrupter/breaker wired to their controller or other protection that meets their requirements (and yours).
