Abstract
Technical BriefsGas-fired and air-cooled generators are subjected to continuous start-stop-load cycles related to thermal/mechanical stresses, and continuous vibration. The machines are designed to run at highly efficient material use and close to its design limit. One big concern relates to hot spots in the stator core where thousands of insulated carbon steel laminates are tightly pressed and clamped together. Damaged insulation can cause large Eddy currents to flow leading to core damage or machine shut down
