Abstract
Electrical current damage is a problem known for a long time. But until now we have never met this problem in our gas turbine engines. The article deals with our experience in diagnostic of this event and solution of bearing protection problem and measures of dielecrtric resistance increase by means of bearing ceramic coating and the use of hybrid bearings.
