Number of breaker operations possible...
(OP)
I am trying to find out what the typical number of open/close/open/close operations is possible for a high voltage circuit breaker (>69 kV). Many of the higher voltage circuit breakers are blast type breakers and are limited to just a few operations until the compressor can recharge. In my experience no more than four operations is the norm--what is the word on this from you folks?
Thanks!
Thanks!






RE: Number of breaker operations possible...
I seem to remember a certain make of hydraulically operated OCB that was expected to make three operations from fully charged if power to the pump was turned off, but it's been some years since I worked with that. I twas in their literature, though.
