Abstract

A system for monitoring parameters of load equipment is provided. A power connector is provided with intelligence, at least one sensor, and a wireless communication component. The power connector is capable of monitoring physical parameters measured by the at least one sensor, such as voltage, current, temperature, and moisture. The system can further provide an alarm if the sensed parameter falls out of a predetermined range.
