Improved NEPA Substations On-Line Monitoring Technology Using Optical Fiber Sensors

Abstract

Condition monitoring of power substations is a significant issue for the National Electric Power Authority (NEPA) of Nigeria. Current methods for monitoring the condition of high voltage equipment are time consuming and often inaccurate, therefore causing catastrophic damage to the substation equipment. Recent research has demonstrated the efficacy of employing optical fiber sensors in condition monitoring of substation equipment. These sensors enhance the current monitoring method and facilitate faster responses to equipment problems. This paper briefly reviews the state of the arts, but is primarily devoted to a discussion of the new approach and future directions in condition monitoring of NEPA substation equipment.
