![]() “Not only has the customer boosted its security level by increasing the thermographic sampling from four times per year to over 26,000 times per year, it has also received a significant insurance premium discount because of this increased reliability,” Robin Thompson confirms. An image is collected every 20 minutes, capturing high, low, mean and median temperatures for each measuring point. These cameras are connected to the SensEye AVR software to monitor 12 ‘probe points’ in each camera’s field of view. Here, Sensei installed nine FLIR A310f thermal imaging cameras to monitor eight transformer-circuit pairs and a manually operated disconnector. A typical application is for a large data centre that owns its own substation. When combined with SensEye AVR, the FLIR cameras have now become Sensei’s preferred solution for electric substation condition monitoring and many successful installations confirm the efficiency of this system. The customer concerned wanted a robust system that would address the recurring problem of security breaches and copper thefts but Sensei realised that FLIR infrared technology could also be the ideal method for reading the temperatures of the company’s bushings, breakers and capacitor banks. The condition monitoring concept was developed from a successful Sensei installation of FLIR automation cameras for intruder detection. SensEye AVR analyses on-line data from virtually any substation device, automatically alerts and notifies critical changes in any reading or combination of readings and delivers data to SCADA and enterprise historian servers. The FLIR cameras are teamed with SensEye AVR, Sensei’s video analytics system, which records thermal images as JPEGs and the frame by frame radiometric data captured by the FLIR cameras, allowing for precise pixel-by-pixel measurements. Also, one camera is able to monitor several assets at once.” “This method is non-invasive, eliminates human error and mitigates the risk of greater failures. “Continuous automated radiometry has many benefits,” explains Robin Thompson founder and CTO of Sensei Solutions. Whenever a pre-defined temperature threshold is detected by a FLIR camera, an alarm is generated to a remote operator who can take the appropriate action. The Sensei system is based on a network FLIR fixed mounted cameras and intelligent automation software that monitors critical components continuously without the need for human intervention. It uses infrared inspection but not in the handheld or gimbal mounted sense that has been common in the industry for many years. And since every key component needs a separate sensor, these solutions are often pricey too.Īn alternative, developed by Sensei Solutions, is already proving highly cost effective and dependable. Most of these systems, however, are invasive and complicated and require an outage to install. The Sensei system is based on a network FLIR fixed mounted cameras and intelligent automation software that monitors critical components continuously without the need for human interventionįor utility companies, condition monitoring is becoming essential to ensuring the reliable delivery of electricity and for minimising operational costs and there are many conventional instrumentation and measurement methods available for this purpose.
