06/29/2004 ~ Keys Energy Services (KEYS) transmission and distribution employees have been working diligently to prevent power outages before they occur by repairing more than 90 “hot spots” over the past month and a half.
Universal Thermography, Inc., a company hired by KEYS to perform infrared testing on transmission and distribution equipment between May 10th and June 18th, identified 91 heat anomalies, or “hot spots”, which could be potential failures resulting in power outages. During the study, a special infrared video camera was used to detect these anomalies, which are a red flag for equipment failure.
“Knowing that a component may fail gives us the opportunity to complete corrective maintenance prior to actual failure,” said Roger Rewolinski, director of transmission and distribution. He added that, “our goal is to achieve the highest reliability possible.”
Thus far, approximately half of the 91 anomalies identified have been corrected. The remaining anomalies are scheduled for repair in order of the severity of the anomalies. Repairs can include cleaning, replacing, realigning, recrimping, and rewiring electrical connections.
KEYS performs an infrared survey on a yearly basis in order to identify and repair anomalies. This is the ninth year that KEYS has completed an infrared study.
