Past EPRI Work on Topic
| Product ID | Title | Description | Published Date |
|---|---|---|---|
| Live Working Reference Book(The Tan Book): 2025 Edition | The Tan book provides the utility industry with a single, comprehensive, technical resource related to work on energized circuits which is the performance of maintenance, construction, or testing on equipment and circuits that are energized or that may become energized. | 12/31/2025 | |
| Minimum Approach DistanceCalculator (Software) | The Minimum Approach Distance(MAD) Calculator is used to find the closest distance a qualified electrical worker is permitted to approach either an energized or a grounded object, as applicable for the work method being used. The software uses both IEEE and IEC calculation methods. The software also calculates the minimum number of good insulators for live line work. | 12/31/2025 | |
| Insulating Ropes for Live Working: Thermoplastic Extruded Jacketed Ropes, Fall Arrest Performance, and Stringing Lines | This technical update presents preliminary electrical and mechanical standard and exploratory testing results of thermoplastic extruded jacketed ropes. Additionally, the report includes testing results of ropes exposed to rope grab fall arrest and investigates the electrical performance of synthetic ropes used in stringing operations in energized environments. | 12/31/2025 | |
| 3002030126 | Calculating Rating of Temporary Grounding Cables (Software) | The Rating of Temporary Grounding Cable (RTGC) calculator is a software that enables utility personnel to quickly calculate and select the appropriate temporary protective grounding (TPG) cable size for different fault conditions, including initial and final cable temperatures, current magnitude, X/R ratio, and angle of fault current initiation. | 12/31/2024 |
| 3002029592 | Insulating Tool Flashover Investigation: Model Development and Analysis Using Time-Domain Modeling | This technical update describes the development, and the results of a finite-Difference time-domain(FDTD) model based on a scientific paper developed by Chalmers University in which a finite element model (FEM) was used to reproduce a flashover eventthat occurred across a strain link stick in a 230-kV AC transmission line. | 12/31/2024 |
| 3002027012 | Guide for the Temporary Protective Grounding of Overhead Transmission Lines | This report addresses temporary protective grounding and bonding performed during the construction and maintenance of de-energized OHTLs. It includes many topics such as grounding principles, step-and-touch potentials, components of grounding equipment, methods of installation, vehicle and stringing site grounding, lessons learned, station ground switches, and segmented shield wires. | 12/31/2025 |
