3.7.2 [Source]/[Busbar] L# wire break
Controller types: GENSET, SHAFT generator, SHORE connection and BUS TIE breaker controllers
These alarms alert the operator to a measurement failure on a phase:
• [Source] L1 wire break
• [Source] L2 wire break
• [Source] L3 wire break
• [Busbar] L1 wire break

• [Busbar] L3 wire break
The controller only activates the alarm when all of these conditions are met:
• The generator breaker is closed
• Voltage is detected by one set of ACM voltage measurements
• No voltage is detected on one of the phases for the other set of ACM voltage
