Page 7: About The Product
— — Introduction CPS- MM-LC Reference Manual (Hardware) 3. About the Product This product is a module to monitor leakage current of the equipment in a live state that is driven by three-phase alternating current power. Set this module to operate along with the CONPROSYS series configurable type CPU module controller. -
Page 8: Features
— — Introduction CPS- MM-LC Reference Manual (Hardware) 4. Features 1. Hardware features Find isolation deterioration in motor This product finds isolation deterioration of the three-phase induction motor by calculating isolation resistance from the measured applied voltage as well as ground fault current to the three-phase induction motor (three-phase motor). With the Modes-IO measurement method, isolation resistance in a live state can be accurately measured, and it is applicable to detect isolation deterioration of the three-phase induction motor. -
