The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

Neoptix Fiber-Optic Sensors has introduced its T/Guard Direct Windings Monitoring System standard with large backlighted LCD and MODBUS RTU communication. Neoptix T/Guard now features a standard four ...

Weschler's line of transformer and LTC temperature monitors has been further enhanced with the introduction of new three-winding capability Weschler's line of transformer and LTC temperature monitors ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

Transformers for power applications often are limited in size by an acceptable temperature rise. An acceptable temperature rise of a transformer is usually dependent on limitations of the materials ...

• The thermal models that servomotor manufacturers provide may not hold for brief periods of superhigh torque. • More accurate thermal models for periods of high performance use equations with more ...
