Reliable Bearings for the Power Generation & Renewal Energy Industry

Renewable and alternative energies are at the forefront of the global conversation about sustainability. More than ever, alternative power sources like solar and wind farms, and geothermal and nuclear plants need the public to feel they are dependable and worth the investment.

When components like motor bearings or pump seals fail in any of these applications, the fix is not easy. The coordination of resources and time needed to address a motor issue involves teams of workers to execute. And the unplanned downtime is even more expensive. So a turbine or cooling tower can’t be offline for long, and for the safety and fiscal health of everyone involved it is far better to not worry about any disruptions.

Generator operators around the world have recognized the value of AEGIS®️ Rings as another layer of protection against downtime. So AEGIS®️ rings are used in generation facilities in a wide range of power generating applications, to protect motors and generators against electrical bearing damage, and to mitigate electrical erosion of pump seals.

Geothermal

Geothermal plants don’t need battery banks to match power generation for demand. Instead, they rely on variable frequency drives to regulate the speed of large power generators and various sub-systems including deep-well line shaft pumps for district heating.

Nuclear

Stray voltages can build up on RRP/RCP motor shafts and lead to currents which electrically erode face seals necessitating an unplanned shutdown.

By providing a highly reliable electrical path from shaft to seal housing, specially designed AEGIS® rings safely neutralize the electrical potential difference between the pump shaft and the seal housing, preventing harmful shaft voltages.

Measurements on a wind turbine for a generator on a 140m high turbine with a rotor blade  diameter of 135m showed a dangerous peak-to-peak shaft voltage. After installing AEGIS rings the residual shaft voltage decreased to a safe level.
