Six differential stator-phase-fault protection (87) for all size generators (you MUST know)
Generally, phase faults at generators rarely occur, but when they do, large fault currents can flow and make a mess. The best protection is differential (ANSI 87), and this type is recommended for all generators, except maybe for small units… Read more

Protection of three-phase motors from unbalance (loss of phase and phase rotation)
The most common cause of unbalance for three-phase motors is the loss of phase resulting from an open fuse, circuit breaker, connector, or damaged conductor. Unbalances in other connected loads can also affect the motor. A voltage unbalance of 3.5%… Read more

Electrical insulation testing – Often underestimated until things go really bad
Due to mechanical damage, vibrations, (excessive) heat/cold, moisture/humidity, chemical influences and interactions and aging pinholes, cracks causes moisture and foreign matter to penetrate the surface of the insulation. They create a low resistance path which allows leakage current to flow… Read more
