EPRI Disconnect Monitor: Use case

The problem:

Power utilities often face challenges related to the reliability and safety of electrical disconnect switches. These switches are critical components in the electrical grid, and any failure can lead to significant outages and safety hazards. The primary issue being addressed is the need for continuous monitoring to detect early signs of wear, overheating, or mechanical failure, which can prevent costly downtime and ensure the safety of the electrical infrastructure.

RF monitoring approach:

The RF Monitor was installed on both the movable arm and the stationary jaw side of the disconnect switches. Sensors were used to measure the temperature of the blade and jaw, as well as the inclination and rotation of the arm. The data collected was transmitted wirelessly to a central monitoring system. Algorithms were employed to analyze the data in real-time, and automatic alarms were triggered if any anomalies were detected, allowing for prompt maintenance actions.

Lessons learnt:

The implementation of the RF Monitor provided valuable insights into the condition and performance of disconnect switches. One key lesson learned was the importance of continuous monitoring in identifying potential issues before they lead to failures. The data collected helped in understanding the typical wear patterns and failure modes of the switches, enabling more targeted and effective maintenance strategies. Additionally, the use of wireless data transmission proved to be reliable and efficient, reducing the need for manual inspections.
