For networked CBMs, BreakerView provides status of each networked CBM. If so desired, BreakerView can be launched within a SCADA system. Alternatively, an individual CBM can be connected to by use of a laptop with BreakerView application connected via USB cable to the EIM.
20 degree angle of the associated Circuit Breaker Monitor infrared window line of sight. The shortest distance from the CBM to the IRIM (when the breaker is in the racked out position) will determine the most restrictive placement of the IRIM.
Any operational performance assigned. With this methodology, any circuit issues are identified and diagnostics with breaker with an embedded CBM will be corrective actions provided. Recording of identified with its switchgear location, thus events is provided in the embedded database.
