a plurality of gas detectors mounted above the equipment service cabinet, and each capable of detecting a presence of airborne particulates; and
a local monitoring computer system operatively connected to said cameras and said gas detectors and adapted for receiving, storing, and analyzing data inputs for purposes of raising alarms and providing a remote indication of potential failure conditions to a remote monitoring system.
2. An electrical equipment service cabinet equipped with a monitoring system for remote inspection and monitoring, comprising:
an electrical equipment service cabinet having a roof, a floor, and a deadfront wall supporting one or more mechanical dial gauges, electrical terminations and bushings;
a digital camera, mounted within the electrical equipment service cabinet, that is capable of capturing wide angle images of the deadfront wall, the floor, or both, in low visible-light conditions of the electrical equipment service cabinet, wherein such images include images of the one or more mechanical dial gauges, electrical terminations and bushings;
a gas detector, mounted at a top of the electrical equipment service cabinet, that is capable of detecting a presence of airborne particulates; and
a monitoring computer system operatively connected to the camera and the gas detector and adapted for receiving, storing, and analyzing data inputs from the camera and the gas detector for purposes of raising alarms and providing an indication of potential failure conditions.
3. The monitoring system-equipped cabinet of claim 2 , wherein the digital camera is mounted on a motorized swivel.
4. The monitoring system-equipped cabinet of claim 3 , wherein the motorized swivel positions the digital camera to capture separate images at a plurality of different orientations.
5. The monitoring system-equipped cabinet of claim 4 , wherein the motorized swivel positions the digital camera to capture, at a first orientation, an image of at least one of the one or more mechanical dial gauges supported on the deadfront wall, and, at a second orientation, a separate image of other relevant equipment contained in the cabinet, including equipment on the floor of the cabinet, such equipment including at least one electrical termination or bushing.
6. The monitoring system-equipped cabinet of claim 2 , wherein the cabinet includes a primary cabinet and a secondary cabinet, the primary cabinet and secondary cabinet being separated by a partition, wherein the digital camera is a first digital camera that is mounted in the primary cabinet, and wherein the monitoring system-equipped cabinet includes a second digital camera mounted in the secondary cabinet.
7. The monitoring system-equipped cabinet of claim 2 , wherein the digital camera images relevant parts of equipment on the deadfront wall, floor, or both.
8. The monitoring system-equipped cabinet of claim 7 , wherein the images are adapted for identifying leaking in the form at least one of vertical traces, expanding pools, and darkening concrete floor.
9. The monitoring system-equipped cabinet of claim 2 , wherein the digital camera images the one or more mechanical dial gauges.
10. The monitoring system-equipped cabinet of claim 2 , wherein the cabinet includes a primary cabinet and a secondary cabinet, the primary cabinet and secondary cabinet being separated by a partition, wherein the gas detector is a first gas detector, mounted at a top of the primary cabinet, and wherein the monitoring system-equipped cabinet includes a second gas detector mounted at a top of the secondary cabinet.
11. The monitoring system-equipped cabinet of claim 2 , wherein the monitoring computer system compares images from the digital camera to baseline images.
12. The monitoring system-equipped cabinet of claim 2 , wherein the gas detector is a first gas detector, wherein the monitoring system-equipped cabinet includes a second gas detector mounted in a lower portion of the cabinet, and wherein the second gas detector detects ozone resulting from electrical arcing events inside the cabinet.
13. The monitoring system-equipped cabinet of claim 12 , wherein the cabinet includes a primary cabinet and a secondary cabinet, the primary cabinet and secondary cabinet being separated by a partition, and wherein the gas detector is disposed in the primary cabinet.
14. The monitoring system-equipped cabinet of claim 13 , wherein the gas detector is disposed adjacent the one or more bushings.
15. The monitoring system-equipped cabinet of claim 13 , wherein the gas detector is disposed on the partition.
16. The monitoring system-equipped cabinet of claim 2 , wherein the one or more mechanical dial gauges include a temperature gauge.
17. The monitoring system-equipped cabinet of claim 2 , wherein the one or more mechanical dial gauges include a cabinet pressure/vacuum gauge.
18. The monitoring system-equipped cabinet of claim 2 , wherein the monitoring computer system is a local monitoring computer system disposed within the electrical equipment service cabinet.
19. The monitoring system-equipped cabinet of claim 2 , wherein the digital camera is capable of capturing wide angle images.
20. A system for remote inspection and monitoring of an electrical equipment service cabinet having a roof, a floor, and a deadfront wall, comprising:
a digital camera, mounted within the electrical equipment service cabinet, that is capable of capturing wide angle images of the deadfront wall, the floor, or both, in low visible-light conditions of the electrical equipment service cabinet;
a gas detector, mounted at a top of the electrical equipment service cabinet, that is capable of detecting a presence of airborne particulates; and
a local monitoring computer system disposed within the electrical equipment service cabinet, operatively connected to the camera and the gas detector, and adapted for receiving, storing, and analyzing data inputs from the camera and the gas detector for purposes of raising alarms and providing a remote indication of potential failure conditions to a remote monitoring system.
