Hardware Design of Network Model of Protection and Controller module for Three-Phase Induction Motors in Industrial Plants with Remote Monitoring System on a Centralized System

Manufacturing Industries uses various equipments to perform its tasks, these instruments are controlled simultaneously at a centralized monitoring station. The instrument sends the task progress and measured values from various sensors to the central monitoring system via a local area network (LAN). Operational instructions are sent from the system to the instruments. This paper explains the design, development and troubleshooting of hardware design of network model of fault prevention and remote control of three-phase induction motors in industrial plant and improvements in module design. The system checks faults in 3 phase induction motor such as incorrect phase sequence, overload current, no-load current, surge voltages, imbalance phase loading & single phasing. Measured electrical parameters, fault conditions and motor performance status are sent to a central monitoring system via TCP/IP protocol in a local area network. Multiple modules can be monitored and operated remotely with a user interface at central monitoring system. Centralised monitoring system enables the user to control, check the performance parameters and record the operation from a remote station.
