EPRI RF Monitors
The EPRI Radio Frequency (RF) Monitor Suite is a collection of monitors that provide information on the health of a range of transmission line and substation assets. |
|
EPRI T&D Asset Forensics & Failure Analysis
Transmission and Distribution (T&D) asset failures can significantly impact system operation, reliability, and safety. These failures are frequently difficult or impossible to predict, and they can sometimes seem random. |
|
EPRI EMP Testing and Design Support Applications
High-Altitude Electromagnetic Pulse (HEMP) has long been identified as a threat to power grids around the world and can disrupt unhardened power systems over large geographical areas. |
|
T&D Asset Analytics Support Applications
Transmission and Distribution (T&D) utilities face several challenges—among them, aging infrastructure, stringent operating requirements, financial constraints, and retiring expertise—that make maintaining and managing power delivery assets challenging. |

Located in Lenox, MA is EPRI’s 138kV research substation. This substation as a multitude of capabilities with a few examples being: on-line monitoring evaluations, ground grid analysis, bushing testing and robotics evaluations. This research substation has the ability to be energized while subjecting assets to various harsh environmental and loading conditions. In addition, with it being a research substation, EPRI is able to follow well defined test protocols. _Click the popover to keep the popover open.-

EPRI Value and Impact: Wood Pole Methodology Delivers Cost Savings
Bhavin Desai Senior Program Manager Transmission and Substations
-
Wood poles are used extensively to support both transmission and distribution class overhead lines.
-
Utilities periodically perform inspections to assess the current remaining strength of the pole and decide whether the pole should be replaced or maintained.
-
EPRI researchers sought to determine how inspection data could be used to improve pole fleet management and how inspection data from multiple utilities may be used to yield industry-wide insights
-
The Transmission Asset Management Analytics program developed an analytical methodology by working with wood pole data from 16 different utilities to better understand the influence of various factors on pole service life.
-
This analysis included data in a dozen separate files detailing approximately 1 million T&D wood poles inspected over 11 to 13 years.
-
Xcel Energy- “This model allows us to determine the projected age of various types of wood poles with and without retreatment and can be used to set up policies on treatments and/or where treatments would not work.”
