Researchers at MIT devise a new monitoring system for electric devices within a factory, ship, or building. The system performs round the clock monitoring of electric devices that are in use. If desired parameters not satisfied, it signals for imminent repairs.
To validate, the monitoring system tested on a Coast Guard cutter for its functioning. As a result, the system pointed out a motor with burnt-out wiring. If missed, the wiring was in a state to have caused serious onboard fire.
Sensor key component of Monitoring System
The new monitoring system uses a sensor. The sensor attached to the exterior of an electrical wire at a single point of contact. To make the attachment, cutting or slicing of wires not required. From the single point, the sensor can sense the flow of current in adjacent wire.
Further, the sensor can detect the distinct signatures of each pump, motor, or piece of equipment in the circuit. It does so by analyzing minuscule, unique fluctuations in the current and voltage when a device switched on or off. The readings of the sensor displayed on an easy-to-use graphic display.
Regarding its capability, the system can do more. It can monitor energy usage, identify possibility of improvement of efficiency, and determine when and where electrical devices are in use or not in use.
So far, the new monitoring system is shown to be suitable for small, contained electrical systems. This includes the one used in small ship, factory, or building with fewer devices to monitor.
Earlier, last year, a series of tests on Coast Guard cutter, the new monitoring system displayed a dramatic demonstration of its capability.
