Abstract
A system is provided in which the voltage phases, neutral, and ground are monitored and an alarm is generated if specific trigger conditions are met. These conditions are indicative of a possible loose neutral, loose wiring, or general over/under voltage condition. Specific algorithms can be used to determine the possibility of a loose wiring condition, and if limits are met, various alarm modes are started.
