Everything You Need to Know About Shaft Grounding Devices
NettetKACO shaft grounding rings meet the high requirements of electric motor manufacturers. Harmful shaft voltages and bearing currents are diverted to the electrical ground to prevent bearing damage and interference noise. This is made possible by a highly conductive PTFE washer with a special coating. Shaft grounding rings, wet … NettetThe grounding system appears to the lightning impulse as a transmission line where wave propagation theory applies. A single point grounding system is achieved when all equipment within the structure (s) are connected to a master bus bar which in turn is bonded to the external grounding system at one point only.
