Breakdowns of the electrical insulation system have been documented to cause catastrophic failure of critical equipment. Partial Discharges (PD) are measured on rotating machines in order to prevent ...

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.

Louisville, CO, October 7, 2013 — Boulder Wind Power (BWP) announced today that the latest test results of its patented printed circuit board (PCB) stator technology prove a clear advantage in ...

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 ...

Motors and generators are critical components of electrical systems. They are used to automate numerous industrial processes, circulate liquids for cooling and lubrication purposes, and generate ...

Partial discharge (PD) is defined as a localized, high-frequency arcing that only partially bridges the insulation between multiple conductors or between conductors and the ground wall of an ...

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 ...

When addressing the operating costs of a modern heavy industrial production facility, most industrial processes will involve electric motors and all will need the services of a generator, either ...

Basic thermodynamic laws tell us that, no matter what its design, in every electric motor some of the input electrical power is undoubtedly lost (via heat) as it is converted to output moving power.

A small 0.75 horsepower, 4-pole, 460 V, Class F AC motor (Figure 1) was chosen for the model rewind. This motor was selected as it is compact in size and has lightweight dimensions to allow easy ...
