Application Skills of Infrared Thermometer in Electrical Equipment
In the following applications, infrared thermometers can effectively prevent equipment failures and unplanned power outages.
The connector electrical connection area will gradually loosen the connector due to repeated heating (expansion) and cooling (contraction) generating heat, surface dirt, carbon deposition, and corrosion. A non-contact thermometer can quickly determine the temperature rise indicating a serious problem.
Electric motor - To maintain the lifespan of the motor, check if the temperature of the power supply connection wire and circuit breaker (or fuse) is consistent.
Motor bearings - Check for hot spots and regularly repair or replace them before any problems occur that cause equipment malfunction.
Motor coil insulation layer - extends its lifespan by measuring the temperature of the motor coil insulation layer.
Measurement between phases - Check if the temperature between the wires and connectors of induction motors, large computers, and other equipment is the same.
The winding of the transformer air cooling device can be directly measured with an infrared thermometer to detect excessive temperature, and any hot spot indicates damage to the transformer winding.
Uninterruptible Power Supply - Determine the hotspot of the connection line on the UPS output filter. A low temperature point indicates that the DC filtering circuit may be open.
Backup Battery - Check the low-voltage battery to ensure proper connection. Poor contact with the battery connector may heat up enough to burn the battery core.
Ballast - Check for overheating before the ballast begins to smoke.
Utilities - Identify hotspots for connectors, wire joints, transformers, and other equipment. Some models of optical instruments have a range of 60:1 or even greater, making almost all measurement targets within the measurement range.
