PX1 enables Power System Security Routine Inspection

Application Background The operating status of electric devices directly affects the operational security and efficiency of power systems. Regular inspection and fault  diagnosis of the operating  status of electric devices can effectively promote the power system to operate more reliably, safely, and economically, thus  minimising the  maintenance cost of the system. Thermal imaging technology has the advantages of no contact, no power failure and large-area rapid detection, which can quickly present the temperature distribution in the area. Functions such as high and low-temperature capture, multi-point temperature measurement, high-temperature alarm, and image storage are supported, which  can detect line defects and abnormalities promptly to ensure the power system’s stable and safe operation.

The Main Applications of Thermal Imaging in Power System Routine Inspection

Transformer Operating Status Detection
As an important part of the power network, the  transformer can affect the normal power supply if it is overheated and experiences failures, leading to high maintenance costs.  Transformer overheating  may be caused by improper installation of devices,  electrical isolation or gradual ageing of mechanical components, and improper setting of operating  parameters. Thermal imaging is  helpful to quickly  locate the overheating   position of a transformer and   detect hidden dangers such  as loose joints, overheating bushings, poor contact, overload, three-phase unbalance, and clogged cooling pipes for timely maintenance.

Temperature Measurement of Electrical Devices in a Power Distribution Room
The electrical device in the electrical cabinet fails during operation due to poor contact,  overload, and other reasons, thus affecting the normal operation of the power system. Electrical contacts, contact switches, line joints, and other critical points of electrical devices in the electrical cabinet must be checked regularly. Once the connections are found to be abnormally heated by thermal imaging due to overload and poor contact, the staff will be promptly alerted for corrective maintenance.

Temperature Measurement of the Generator Carbon Brush
As a sliding contact, the generator brush will  inevitably generate heat during operation, but this heat must be controlled within the normal range. Excessive temperature can cause abnormal operation, which will directly lead to device failure and affect the regular operation of the  generator set. It is necessary to monitor the temperature of carbon brushes regularly by thermal imaging to detect abnormal temperatures in time, ensure production safety and reduce economic losses.

Temperature Measurement of Wind Turbine Cable
At the joint between the anti-torsion cable of the turbine and the ordinary cable, the  air is possibly entering due to the butt joint of the sleeve after cutting. This results in  oxidation of the cable and an increase in resistance during operation. The temperature will rise when the wind is stronger, causing cable fracture and significant economic loss. Thermal imaging technology is used for regular detection to promptly detect the potential breakage risk of cables and reduce financial losses.
