Substation Survey Camera Integrates Thermal, Visual, and Ultrasonic Observation Technologies in a Single On-Line Monitoring Package:
-Australasian Industry already highly excited by the potential contribution to asset integrity and general site security offered by such an economic and comprehensive total-substation monitoring package!!-
Remote HV equipment inspections, coupled with viable intruder / animal pest detection in the switchyard, have become more effective with the combined technologies of Mikron Infrared's new Dual Vision 724 Ultra Remote Monitoring System for substations. The system is the first to combine visual and high resolution infrared cameras with airborne ultrasound to provide a truly comprehensive package geared toward the remote monitoring of substations and the detection of potential problems including arcing, tracking, or corona conditions.
The Dual Vision 724 Ultra system consists of airborne ultrasound and separate thermal imaging and video cameras, all in an environmentally sealed, temperature-controlled enclosure. With Internet IP addresses and password protection, the system can be controlled from any computer using wired or wireless Ethernet.
Utilized with Mikron's MikroSpec™ Dual Vision Ultra R/T software, the system can produce thermal images to aid in the detection of heat-related conditions and can also produce sound files to detect arcing, tracking, or corona conditions, which typically cannot be seen with the use of infrared. Up to 32 regions of interest (ROI's) can be defined on the thermal image in any complex shape (eg: around the whole of a HV CT, tap changer, or overhead isolating switch assembly), enabling the system to trigger alarms at the approach of intruders or from temperature excursions on substation hardware.
Combing the 724 with Mikron’s optional companion tilt and pan head can offer enhanced coverage of up to 255 such views per camera, each of these views still offering up to 32 pre-settable regions of interest!!
In addition to the thermal image, the system also has the ability to provide a visual image and allows for the infinite blending of both the thermal and IR camera feeds to create a single Dual Vision image with correct aspect ratio and spatial area. The resulting composite image can then be further adjusted to show any percentage of the IR and visual feeds so the exact locations of particular heat-related anomalies can be easily identified.
The software can record up to 75 minutes of blended visual and IR video to a hard drive when capturing every frame from a camera set at a frame rate of 30 Hz. Total record time can be greatly extended by capturing images at intervals, rather than continuously. Video capture can be triggered by a temperature alarm from one of the ROI's or by direct signal from the PC. A user-selectable pre-buffer of video allows the operator to also capture what happened in a scene before an event trigger.
Multiple camera locations can be monitored at one time from a single PC, and this system can easily be used as a component for an enterprise-wide SCADA system.
