EPRI Lightning and Fault Current Monitor: Use case
The problem:
Power utilities often face challenges related to the detection and analysis of electrical disturbances such as lightning strikes and fault currents. These events can cause significant damage to infrastructure, leading to costly repairs and extended downtime. The primary issue being researched is how to effectively monitor and analyze these disturbances to improve the reliability and safety of power systems.
RF monitoring approach:
The Lightning and Fault Current RF Monitor is installed by clipping it directly onto the power conductor. This non-intrusive installation allows the device to continuously monitor the electromagnetic fields generated by lightning and fault currents. The monitor measures the magnitude and charge of these events and records the precise time they occur. This data is then processed to create histograms, which provide a visual representation of the frequency and characteristics of these disturbances over time
Lessons learnt:
From the research and development of the RF monitor, several key lessons have been learned. Firstly, the importance of accurate and real-time data collection has been highlighted, as it allows for timely identification and mitigation of potential issues. Additionally, the use of histograms has proven to be an effective method for analyzing long-term trends and patterns in electrical disturbances. This has led to a better understanding of the behavior of lightning and fault currents, enabling more informed decision-making for maintenance and infrastructure improvements.
Status:
Currently, the Lightning and Fault Current RF Monitor is still under development and undergoing lab testing. The focus is on refining the device’s accuracy and reliability to ensure it can provide valuable data in real-world applications. Ongoing research aims to further enhance the monitor’s capabilities and explore its potential uses in various power systems. As the development progresses, the device is expected to play a crucial role in improving the safety and efficiency of electrical power distribution networks.
