Used in tandem with a current source, Zensol's SIM-CB is a circuit breaker simulator that tests any type of protection relay (such as CEPA used by the Hydro-Québec electric facility). This unit is software-configurable.
Easy to use, the SIM-CB simulates a circuit breaker during current injection tests on protection relays. SimWin software is available free of charge on the Web site. Upgrades are unlimited and free of charge. The SIM-CB is compact, light and easy to carry.
