CEM Infrared Thermometers Support Power Maintenance in Reducing Carbon Emissions
Driven by the dual goals of "carbon peaking and carbon neutrality" and the development of a new power system, the efficient operation and energy management of power equipment have become key to achieving a low-carbon energy transition.
The CEM DT-8889H Long-Distance Industrial High-Temperature Infrared Thermometer adopts non-contact heat loss detection technology to optimize equipment performance, reduce energy waste, and contribute to carbon emission reduction targets.
The operational dilemma of high-load performance intertwined with safety risks
Power equipment is an important physical foundation supporting the safe and reliable power supply of the power system. With the rapid deployment of new types of power facilities such as ultra-high voltage transmission and intelligent substations, the operating intensity of the equipment continues to increase.
Key equipment such as transformers, circuit breakers, and transmission line joints operate under high load conditions for long periods, and are prone to local overheating caused by poor contact, aging, or overload, leading to equipment failure or even fire. Traditional contact-based temperature measurement requires power outage operations, which are inefficient and pose safety risks.
In complex environments such as substations and high-voltage lines, factors like high temperature, high voltage, and strong electromagnetic interference limit the application of traditional temperature measurement methods. In addition, during nighttime inspections or under severe weather, manually locating heat spots becomes significantly more difficult.
Moreover, traditional manual inspections rely on experience-based judgment, with scattered data recording and lack of real-time capability, making it difficult to meet the intelligent grid's demand for precise and digital monitoring of equipment conditions.
To improve the level of power grid intelligence and support the realization of the “dual carbon” goal, the current operation and maintenance model urgently needs a technological upgrade.
DT-8889H empowers the improvement of power grid safety and energy efficiency.
The DT-8889H is a professional handheld long-distance industrial high-temperature infrared thermometer designed and developed by CEM, integrating the advantages of non-contact temperature measurement, high precision, and safety and efficiency, providing solutions for power equipment condition monitoring, fault warning, and energy efficiency optimization.
Its infrared temperature measurement range reaches from -50°C to 2200°C with an accuracy of ±1%, covering the common temperature range of power equipment and meeting the detection needs from low-temperature environments to high-temperature scenarios. At the same time, it is compatible with K-type thermocouple contact temperature measurement (range: -50°C to 1370°C), enabling flexible switching between contact and non-contact temperature measurement.
The DT-8889H can measure the temperature of key components such as transformer windings, bushings, oil cushions, and circuit breaker contacts non-contact, and will trigger an alarm if the set high or low temperature value is exceeded, facilitating the quick identification of cold hotspots and accurately identifying local overheating issues caused by poor contact, overload, or insulation degradation.
In response to the diversity of materials in power equipment, the DT-8889H’s emissivity adjustment function (adjustable from 0.1 to 1.0) can correct the emissivity differences of different surfaces such as metal contacts and insulating coatings, ensuring data accuracy.
Its 75:1 high distance-to-spot ratio allows temperature measurement of high-voltage equipment from a safe distance, avoiding direct contact risks. The 150ms fast response time improves inspection efficiency, making it especially suitable for periodic checks of large-scale power grids.
During peak electricity usage periods, the temperature differences at busbar connection points can be analyzed by measuring maximum, minimum, difference, and average values, helping to detect loose or corroded connections in advance, assisting in load adjustment strategy formulation, and preventing chain failures.
The DT-8889H's 8-level backlight display and dual laser targeting function assist operators in accurately locating equipment hotspots in low-light environments. By locking the temperature trigger, continuous temperature values of the equipment can be obtained.
The built-in storage and Bluetooth transmission functions allow temperature data with date/time to be stored and transmitted via Bluetooth to a mobile phone or computer for analysis and report generation, in line with the digitalization trend in the power industry.
Conclusion
In the context of the "dual carbon" goals and the digital upgrade of the power grid, the CEM DT-8889H long-distance infrared thermometer is not only a temperature monitoring tool, but also a core enabler for promoting the safe, efficient, and green transformation of the power system, ensuring that every kilowatt of electricity flows with the promise of safety and a green future.
