System for visual monitoring of operational indicators in an electric power system
First Claim
1. A system for visually monitoring the state of various operational indicators present in an electric power control or monitoring environment, including a substation, comprising:
- means for obtaining an image of the status of a plurality of operational indicators in said electric power control or monitoring environment, wherein said image-obtaining means is positioned in a control house portion of the substation, aimed at indoor targets which include said operational indicators;
means for processing the image so as to enhance recognition of the status of the operational indicators; and
means for comparing the resulting processed image against a preselected standard to determine the state of the operational indicators.

Abstract
A visual monitoring system for an electric power substation includes at least one camera for obtaining the image of various operational indicators in the substation, either within the control house, outdoors or both. The indicators could be the status of various gauges, including current, voltage and temperature gauges, or other structural elements, such as the position of various switches, the level of oil in a transformer sight glass, or whether a transformer fan is running, among others. The image is then enhanced to accentuate the desired features, and the desired data is then image detected. The resulting information is then compared against a standard to determine whether or not the operational status of the indicator is abnormal.
