Two EPRI generator studies still guide maintenance today: rotor failures, flux probe monitoring, and PD/EMI testing explained ...
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 ...
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 ...
