Abstract:
A system for controlling and monitoring electrical energy loads includes a current transducer configured to monitor values of electrical current in the system, wherein neutral and ground lines are monitored via separate current transducers. Additionally, the system includes a centralized programmable logic controller (PLC) configured to receive measured values from the current transducer in real time and a local PLC configured to receive the measured values from the centralized PLC. Further, the local PLC periodically compares the measured values of the electrical energy with predetermined thresholds and automatically redistributes the electrical energy to electrical energy loads among three phases based on the comparison.
