A resistance to ground monitoring system for a magnetic bearing is disclosed. The system includes a dummy bearing arranged in a cooling loop and having a dummy bearing coil made up of an electrical winding that is configured to detect the resistance to ground for the dummy bearing coil. The electrical winding is communicably coupled to a sensing device that monitors the resistance to ground for the dummy bearing coil. Since the magnetic bearing is arranged within the same cooling loop, the resistance to ground for the dummy bearing coil is indicative of ...
1. A magnetic bearing monitoring system, comprising: one or more radial bearings arranged within a casing, each radial bearing having radial bearing coils configured to levitate a rotatable shaft;a cooling loop configured to circulate a cooling gas to the bearing cavities;a dummy bearing arranged in the cooling loop and having at least one dummy bearing coil made of an electrical winding; anda sensing device communicably coupled to the electrical winding to monitor a resistance to ground for the at least one dummy bearing coil, wherein the resistance to ...
