EPRI Structure Blast Monitor: Use case
The problem:
Power utilities often face challenges related to the impact of nearby blasting or demolition activities on critical infrastructure such as transmission lines and substations. These activities can induce vibrations and stresses that may compromise the structural integrity and safety of these assets. To address these concerns, utilities need reliable methods to monitor and evaluate the effects of such external activities on their infrastructure.
RF monitoring approach:
Foundation Structure Blast RF Monitors are installed on foundations, structures, and cabinets to measure the magnitude of vibrations caused by nearby blasting or demolition. These devices use sensors to detect vibrations and transmit the data wirelessly to a central monitoring system. This setup allows for real-time analysis of the impact on the structures, enabling utilities to take timely action if necessary.
Lessons learnt:
From the research and application of these RF monitors, utilities have learned the importance of continuous monitoring and data analysis. The real-time data provided by these devices helps in understanding the immediate and long-term effects of blasting activities. It has been observed that proactive monitoring can prevent potential damage and reduce maintenance costs by identifying issues before they become critical.
Status:
Currently, the use of Foundation Structure Blast RF Monitors is expanding as more utilities recognize their benefits. Ongoing research focuses on improving the accuracy and reliability of these devices, as well as integrating them with other monitoring systems for a more comprehensive approach to infrastructure management. The latest projects continue to demonstrate the effectiveness of these monitors in safeguarding critical infrastructure from the adverse effects of nearby blasting and demolition activities.
