Solution Example (Manufacturing Industry) - Detection of Fault Precursors in Three-Phase Motors
It is now possible to measure the insulation resistance of a three-phase motor while it is running, which previously required the device to be stopped!
【System Description】 Three-phase motors are used in many movable machinery devices such as machine tools, water distribution pumps, and elevators. The insulation resistance of the stator coils in three-phase motors decreases over time, leading to ground faults, phase-to-phase short circuits, and rare shorts, which can result in dangerous conditions that cause equipment failure. If the equipment fails, it not only halts operations but can also lead to accidents that endanger human lives. By using the CONPROSYS(R) insulation deterioration monitoring module, it is possible to continuously monitor the insulation deterioration of three-phase motors and detect signs of impending failure. 【Recommended Product】 ● CONPROSYS(R) Insulation Deterioration Monitoring Module This module calculates insulation resistance by measuring the applied voltage and ground fault current to three-phase induction motors (three-phase motors). It enables accurate calculation of insulation resistance while the system is live, making it useful for detecting insulation deterioration in three-phase induction motors. It can be connected either before or after the inverter.
