Abstract
The electrical equipment failures of both nuclear and
nonnuclear public utilities were reviewed. Those failures that could pose an additional problem to surrounding and connected
equipment were defined.The literature was searched;
utilities, repair shops, and large electrical equipment users
were contacted or failure information. The data were reviewed
in detail, and failure modes were determined. Sample
cascade failures are discussed. The failure rate of electrical
equipment in utilities is historically quite low. Nuclear plants record too few failures to be statistically valid, but failures that have been recorded show that good design usually restricts the failure to a single piece of equipment.
