Shaft grounding devices minimize the shaft voltage and prevent bearings damage caused by the circulating current. There are numerous reasons for developing shaft voltage in the motor. The main reasons for developing shaft voltage are as follows. Leakage Induction High frequency circulating currents caused by VFD

EICS Technology Shaft Grounding Device are designed to ensure that a complete The Shaft Earthing System is essential for any vessel that has installed 

The Propeller Shaft Grounding (PSG) system is installed on propeller shafts to insure a path of low resistance. Protecting your precious equipment.

The shaft earthing assembly comprises a pair of high silver content / graphite compound brushes mounted in balanced brush holder, running on a copper slip ring with solid silver inlay track. Each brush holder has a adjustable spring tensioner which is supplied preset to the minimum, and results in a pressure of 225g/cm2.

Shaft earthing device marine A turning propeller is electrically insulated from the hull by the lubricating oil film in the bearings. Electrical potential is generated between the shaft and the hull. As a result the cathodic protection of the ship will not protect the propeller.

Furthermore, because the grounding brushes also are the coupling point of rotor earth fault protection, reduced grounding functionality can cause false earth 

Checking the earthing device must be done when the shaft is rotating at sea and should be carried out once a month. Release the earthing brushes from their co ntact with the slip ring; this should give high pulsating voltages of 100- 400 mV reading on the meter. This indicates that the measuring circuit is in order.

The earthing system is the basis for the safe function of every electrical system and its protection devices. It ensures operation and protects people against 

To protect the bearings from harmful currents the bearings are electrically insulated and the shaft equipped with an earthing device. The earthing devices that are normally used are based on metal to metal contact which requires a lot of maintenance, or based on micro-fibers which are costly and restricted by export control regulations.

When the shaft earthing set is working properly, the mV-meter should indicate a value below 50mV. Exceeding the 50mV means malfunction of the PSE system, which may be related to filthy or worn parts, or incorrect installation. Additionally the monitoring set can be supplied with a 4-20mA converter that offers an additional alarm function.

We recommend installing the shaftline earthing device in as dry, warm, well-ventilated, and easy-to-access environ-ment as possible, preferably close to the engine. If a shaft generator is installed, install the device forward of the gen-erator, i.e. between the generator and the engine flywheel. When installing and maintaining the device
