Historically, generator inspections require rotor removal (Figure 1). There’s a significant level of risk during this process due to possible generator damage during the disassembly, and it also ...

A crucial factor to consider when planning maintenance of high-voltage (HV) motors and generators, especially those in critical industrial applications, is the life expectancy of the stator windings.

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 ...

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.
