Application skills of electrical equipment for infrared thermometers
In the following applications, infrared thermometers can effectively prevent equipment failures and unplanned power outages.
Connectors—Electrical connections can gradually loosen connectors due to repeated heating (expansion) and cooling (shrinkage) to generate heat, or surface dirt, carbon deposits, and corrosion. Non-contact thermometers can quickly identify temperature rises that indicate a serious problem.
Motor - To preserve the life of the motor, check that the power connection wires and the circuit breaker (or fuse) are at the same temperature.
Motor Bearings - Check for hot spots and repair or replace them regularly before problems cause equipment failure.
Motor Coil Insulation - Extend the life of your motor coil insulation by measuring its temperature.
Measurements Between Phases - Checks that wires and connectors in induction motors, mainframe computers and other equipment are at the same temperature between phases.
Transformer - Windings of air-cooled devices can be measured directly with an infrared thermometer to check for excessive temperatures, any hot spots indicate damage to the transformer windings.
Uninterruptible Power Supply - Identify hot spots on the connecting wires on the UPS output filter. A cool spot may indicate an open circuit in the DC filter line.
Backup Battery - Check the low voltage battery to make sure it is connected properly. Contact** with the battery terminals may heat enough to burn the battery core rods.
Ballast - Check for overheating of the ballast before it starts smoking.
Utilities - Identify hot spots for connectors, wire splices, transformers and other equipment. Certain models of optical instruments have a range of 60:1 or even greater, bringing almost all measurement targets within range.
