Abstract: A method is disclosed of performing point on wave switching in a multiphase electrical system having a first circuit breaker connected a first bus, the first circuit breaker being operated by a first controller, a second circuit breaker connected to a second bus, the second circuit breaker being operated by a second controller, and a subsystem transferred from the first bus to the second bus. The method can include receiving, by the second controller, system characteristics data of the subsystem, estimating, by the second controller, a time for switching based on the received system characteristics data of the subsystem and operating time of the second circuit breaker, and operating, by the second controller, the second circuit breaker at the estimated time for switching, for switching the subsystem.
