Weschler's line of transformer and LTC temperature monitors has been further enhanced with the introduction of a new three-winding capability. With this option, users can display current and ...

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 ...

For safe, long-term use of a compressor, the motor winding temperature must be kept below certain limits, in all conditions in which the appliance may operate. For example, compressors from AC ...

Two-parameter motor models assume that the entire motor exhibits one dynamic temperature. Four-parameter thermal models are just as easy to use, but far more accurate — and better for calculating ...

Maximum temperature ratings are based on the motor’s insulation system class and apply to the winding temperature at the hottest spot inside the motor. As a general rule, the frame can be 20°C to 40°C ...

The LumaSMART winding hotspot temperature monitor builds on the ruggedness, reliability and stability pioneered by its predecessor products such as the WTS-22 and ThermAsset2. The LumaSMART is the ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

Build in a thermal safety margin to handle servomotors that heat up more than theoretical models predict when the torque cranks up. • The relationship between intermittent and continuous torque is ...
