The operation of an electric motor is typically simple and reliable, making it possible to overlook during day-to-day maintenance practices. Having a checklist makes it easy to know exactly wh ...

Aging-Aware Thermal System Control The dynamic operation requirement for grid flexibility provision (e.g., load shifting and frequency regulation) can cause accelerated aging of electric motors. For ...

Insulation life decreases by half for every 10°C increase, so the 20°C temperature increase would reduce the potential life of the electric motor to 25% of its original potential.

MCA allows the analyst to view the simple resistance, complex resistance, inductance, phase angle, ground insulation condition, and other tests to determine the condition of the electric motor ...

Thus, the electrical-winding insulation must have a maximum hot-spot temperature value exceeding the maximum continuous-winding temperature. The greater the safety margin for the hot-spot ...

Insulation resistance (IR) testing is widely used to assess the condition of insulation in such things as service cables, feeder cables and the wiring in major branch circuits. It’s also used to ...

This article describes the testing results following routine performance assessment of an electrical motor both in its original state and after rebuilding it using products made by Zeus, such as the ...

Compressor burnout is a very specific mode of failure that may be caused by high temperatures in the motor windings or discharge area of the compressor. High temperatures break down the motor winding ...
