Abstract: | Disturbance of the grounding of the shaft of a turboset or its absence for technical reasons can result in failure, misoperation,
limitation of the operating zone, errors or limitation of the sensitivity of devices for control and protection of exciting
circuits from single-point leakage, and electroerosion of elements of the turboset structure. Measures for increasing the
reliability of the grounding of the shaft are discussed.
