Zero Current

This alarm indicates that the load current value is 0 A. On polyphase circuits, the alarm happens if the current of one of the phases meets the above condition. The gateway manages the alarms based on the values of the currents sent by the wireless device. The response time of the alarm depends on the communication period set into the PowerTag system wireless network (default = 5 seconds). Zero current alarm allows the monitoring of full time running loads. The alarm automatically disappears when the load current is greater than 0 A on all phases.
