Over the past decade, since industry deregulation, the typical utility power plant has lengthened the maintenance intervals of its major systems to minimize downtime and costs. Many plants schedule ...

Major Inspection of a 330H gas-turbine generator indicated that a stator rewind was needed. The unit failed electrical tests and had suffered with indications of heavy wedge slot and bar tie greasing.

Doble Engineering has introduced an innovative approach to test generators, motors, exciters, isophase bus, switchgear, transformers, and power cables – Electromagnetic Interference (EMI) Diagnostics.

Large electrical generator stators are normally cooled by water. Unfortunately, generator availability is reduced when copper corrosion products plug the hollow strands of the stator-winding coil.

To meet the demand for drive motors / generators needed for hybrid vehicles, engineers at Remy International Inc. designed a line of off-the-shelf devices that are said to have the highest ...
