Challenges while testing magnetically-actuated vacuum circuit breakers
In traditional control circuits, actual volt-amperes (VA) are applied/injected to the command coils. However, when testing magnetically-actuated vacuum circuit breakers, only a "lower power" voltage signal is required. Instead, we need to interface with "Remote TRIP" and "Remote CLOSE" pins (5, 7, and 9) with the associated control
