EPRI is conducting research and development in a wide range of areas related to sensors. Detailed summaries of individual projects are listed below alphabetically by area.
Transmission Line Projects
In addition to developing a suite of Transmission Line sensors, EPRI has been testing and evaluating a range of other sensor technologies.
This project is developing and demonstrating low-cost RF sensors to assess conductors and compression connectors on overhead transmission lines.
This project is developing an RF sensor that is installed either on the shield wire or the down conductor of a transmission line to continually measure the magnitude and time of both fault and lightning currents.
This project is developing image processing cameras that can be installed on transmission lines to automatically measure and report activity.
This project is developing an RF sensor that clips onto the end of a transmission suspension insulator string to measure the leakage currents flowing on the insulator.
This project is developing a suite of low-cost RF sensors that measure vibration in three axes. The sensors can report the results in real-time or store the results for future analysis.
Underground Transmission Projects
This project is developing an RF sensor for measuring oil pressure in components, such as oil-filled terminations. The RF sensor uses a 4-20mA input so the sensor can be applied in a range of other applications.
This project is to investigate, evaluate, and demonstrate technologies in extruded dielectric transmission cable system monitoring.
The project goals are to explore improved techniques and algorithms for diagnosis of power transformers using Acoustic Emission.
Condition monitoring of substation equipment has an inherent value based on preventing failure; maximizing future operation of the equipment; appropriately scheduling and determining the extent of inspections and maintenance; providing for personnel safety; and protecting the environment.
EPRI has a network of sensors on the neutrals of large network transformers that are susceptible to GICs (Geomagnetically Induced Currents).
The project goal is to develop a solid-state Hydrogen and Acetylene sensor for detecting these fault gasses within oil-insulated systems such as transformers, cables, or instrument transformers.
The project's goal is to perform field demonstrations of the concept of on-line Frequency Response Analysis (FRA).
This project is developing an RF sensor that is installed at the base of either substation or transmission line post-type insulators.
The project goal is to investigate the capabilities of pressure, temperature, and density sensors to accurately measure low levels of SF6 leakage.
The project goal is to quantify and trend the RF signals across a large substation. The project concept is to adapt wireless mesh sensors (see project summary for Wireless Mesh) to be able to measure the local RF signals.
The project goal is to perform field demonstrations of wireless acoustic sensors to assess the benefits for diagnostics of substation apparatus
The project goal is first to explore the various power management approaches suitable for large lower-power wireless mesh deployments.
This project is to investigate the feasibility of robotic tools to inspect and maintain components within an underground cable vault.
The aim of this project is to develop a laboratory with a collection of sensors and sensor-enabling technologies for use with EPRI sensor-related projects.
The project aims to provide a standardized access to sensor data for utility RTU/SCADA systems, archive sensor data in local substation databases, and to provide advanced visualization and user interfaces.
