Brief Introduction

The thermometer of a 4 pole three phase induction motor should be properly distributed in the motor windings, and the number should be not less than 6. Under safe conditions, the thermometer should be placed in the position that may be the most hot spot as far as possible, and effective measures should be taken to prevent contact with the primary cooling medium. The maximum reading of the components of the embedded thermometer (ETD) should be used as the basis for determining the winding temperature.

Setting the temperature gauge (ETD) components and connectors may fail and give incorrect readings. Therefore, if one or more readings are incorrect, they should be deleted if confirmed by investigation. The thermometer shall be placed in the slot at the expected hot spot between the insulated coil edges.

Only one coil edge thermometer per slot shall be located at the expected hot spot between the slot wedge and the outside of the winding insulation, see also 8.6.1. The thermometer shall be located at the expected hot spot between two adjacent coil edges at the end of the coil. The sensitive point of the thermometer should be in close contact with the surface of the coil side, and there are sufficient protective measures to prevent the influence of the cooling medium.

When placing the thermometer at the end of the high voltage motor winding, it should be fully considered that the insulation strength will not be affected and the potential difference in the overhanging part of the winding will cause problems. In addition, the grounding measurement system is directly coupled to the high voltage system, and disconnecting the grounding measurement will immediately cause overvoltage of the measuring system. The measurement system should prevent such collateral damage until fatal injury.

Note: If the stator windings are of the direct liquid cooled tube type, the thermometer is placed in the outlet nozzle area of each monitoring water temperature to give an indication of whether the conductor channel is blocked.
