THERMAL AND VISUAL ASSET MONITORING
Continuous thermal monitoring systems anticipate, detect and respond rapidly to problems, thereby reducing maintenance costs, failures, outages and lost productivity. Detection of temperature increases in equipment using thermal cameras allows maintenance to be performed before a failure and unplanned shutdown occurs.
Intelligent video systems that utilize thermal cameras enable automatic detection of temperature increases in critical components and equipment. Thermal signatures are analyzed and used to predict potential equipment failures. The video system incorporates sophisticated thermal analytic algorithms to detect anomalies. Thermal rules are implemented to trigger automated alarm and email notification to alert operators of possible issues.
Asset monitoring with thermal imaging cameras is used to monitor operating temperatures of equipment as part of condition based maintenance program. Ensuring that equipment temperatures remain within limits leads to more reliable service and reduced downtime. Detection of hotspots is an indication of problems in the system that can lead to premature aging and failure. Maintenance can be performed when required as opposed to being based on a time-based schedule.
A single thermal camera on a mobile pan/tilt base can monitor multiple assets and areas such as connection points, transformers, bushings, insulators, isolators, arrestors, breakers etc. The camera can be programmed to cycle through a series of pre-set points and run analytics at each position.
Thermal analytics determine:
- Absolute temperature
- Temperature differential
- Temperature rate of change
Visual Asset Monitoring
Visual Monitoring is used to assess the physical condition of remote sites and the assets inside them. Visualization can positively confirm:
- Positioning and action of isolator arms
- Reading gauges
- Detection of arc flash
- Detection of isolator arm movement
- Detection of intruders and wildlife
When the video analytics detect events, whether they are thermal or visual, the system can be programmed to take further action. The automation system sends alerts through email or directly to the SCADA system where other actions can be triggered automatically or by an operator. The points that temperature monitoring system measures can map directly to analog points directly in the SCADA system. The digital inputs and outputs on the Digital Video Server can be connected to communicate with other monitoring or alarming systems.
