Diagnose overheating issues in power equipment with AT20 thermal camera

Iray’s AT20 thermal cameras complies with industrial temperature measurement standards, is small in size, and supports PoE power supply.

How is the infrared temperature measurement equipment used in power inspections?

Infrared temperature measurement equipment not only reduces the risk to operation and maintenance personnel but also improves the work efficiency of inspection. Iray provides a variety of power maintenance products for different application scenarios in the power industry, which can meet the needs of multiple scenarios such as power transmission, transformation, and distribution.

Below, we will introduce in detail the application of Iray AT20 in the power distribution system.

The power distribution system is a power network system that is composed of a variety of power distribution equipment (or components), through which the power distribution facilities to transform voltage and directly distribute electrical energy to end users. The power distribution system can be divided into three parts; high-voltage power distribution system, medium voltage power distribution system, and low-voltage power distribution system. It is mainly composed of substations, switching stations, and power distribution rooms.

Presently, the manual inspection method is primarily and commonly used to meet the customer requirements in the power distribution system scenario. This method has many human factors including, high time-consuming, high safety and management costs, inability to supervise the work of inspectors, inaccurate inspection data, etc. Inspection personnel do not work according to standardised procedures, and it is difficult for management personnel to control the quality of inspection work; inspection personnel have an insufficient definition of defects and cannot accurately and quickly record defects qualitatively and quantitatively; inspection results data collation and circulation lack effective methods. The inspectors have a heavy burden.

There are many kinds of faults in power equipment but most of them are caused by heat generation. The AT20 infrared thermal camera is used to efficiently find and solve overheating defects in the power equipment. For example, the temperature monitoring of the electrical equipment in the cabinet is carried out in the important electrical cabinet in the power distribution room through AT20, and the monitoring of key points such as electrical contacts and line joints can be realised uninterruptedly. Once overload or poor contact causes abnormal heating of the contacts, through the thermal camera, the alarm information can be pushed to the staff, and the situation can be checked and confirmed in time.

The main features of the AT20 product are dual-light image display and accurate temperature measurement. It meets industrial temperature measurement standards; it is compact and supports PoE power supply; and it has powerful Web software and WiFi hotspot configuration.

The main advantages of AT20 are:

AT20 infrared detection has the characteristics of long distance temperature measurement, no contact, and no change to the target structure. Non-contact temperature measurement does not affect the measured object. It displays temperature data of points, lines, and areas, automatically captures the hottest spots on the full screen or area, and visually checks the problem points and accurately locates them so that engineers can quickly find solutions.

Realise automatic temperature data collection

Real-time reading of detected temperature data, automatic temperature detection, with software to achieve target temperature data collection, which is convenient for operators to visually analyse the temperature of the contacts in the electrical cabinet and the surface of the cabinet.

Alarm functionality is supported, and abnormal alarm information is provided

By setting the abnormal temperature range, monitoring the temperature of the surface of the cabinet and the temperature of the internal electrical equipment during the heating process, and triggering an alarm when the temperature reaches the set range, prompting the staff to take control.
