Application of CEM infrared thermometer in electrical field
nfrared thermometers are very useful for diagnosis and predictive checks of electrical systems and equipment. Infrared non-contact thermometers have been used in the field of electrical maintenance for over 30 years, allowing you to quickly collect important temperature information. Due to the heat generated by current, temperature monitoring has become an effective method for predicting potential equipment failures. In a survey of electrical repair and maintenance personnel, 100% of those using infrared thermometers reported that by detecting high temperature points, they prevented thousands of dollars in downtime losses and maintenance costs. In fact, insurance companies are encouraging their customers to implement preventive infrared scanning. The CEM infrared thermometer can provide accurate readings within an accuracy range of 0.75-2%, with measurement distances up to 35 feet, depending on the instrument model used. They do not need to be set, and the response time is less than 1 second. These instruments are lightweight, structurally sturdy, and easy to carry.
Infrared non-contact thermometer is suitable for:
Find high temperature points
Preventing arcing and insulation damage
Find the grounding wire in the circuit
Identify the source of annoying tripping
Determine energy loss
Protecting the motor
Check the transformer
Measure temperature from a safe distance
Determine the location of wire damage
Measuring electrical components
A non-contact infrared thermometer can measure the surface temperature of an object from a safe distance. Due to the fact that infrared thermometers measure surface temperature, accurate results can only be obtained when the target is directly visible. Remove the cover plate and housing to expose the object to be measured. Motors, oil filled transformers, and circuit breakers can be directly measured because the surface temperature of their casings is usually related to the internal temperature. Execute the following application sections of your safety preventive maintenance plan to prevent equipment failures and unplanned shutdowns.
In factories, infrared readings can be used to quickly and cost-effectively identify high-temperature points on connectors, cable lugs, transformers, and other equipment. Daily temperature checks help prevent equipment failures and the huge cost of equipment downtime. Conducting on-site inspections of power facilities means regularly measuring the temperature of transformers, cables, and other components that are located at high altitudes and difficult to access. There are several models of Fluke infrared thermometers that have an unbeatable 60:1 optical resolution and can easily measure many targets. If you are working in a petrochemical plant, refinery, or other potentially flammable gas location, you should consider using an infrared thermometer that can be used in hazardous locations.
Explain the results
After obtaining the temperature reading, how can you know when there is an actual problem? To obtain this answer, it is necessary to combine the experience of repair or maintenance technicians with the ratings provided by the equipment and monitored electrical component manufacturers. Electrical equipment manufacturers usually list the maximum allowable temperature on the nameplate.
