30107A: Guide for Asset Replacement Strategies with an Asset Management Plan Leveraging a Risk Based Approach - Phase I

The primary objective of this project is to develop a guide to support investment decisions into substation assets, allowing asset managers to objectively determine when a specific asset warrants replacement, repair or refurbishment by factoring in the condition of the asset, remaining asset life, its function and application in the network, and the potential impacts of the asset failing. The guide outlines the necessary financial and economic principles used to make informed and justified asset

5070: Stability Considerations for the Connection of Generating Facilities to the Distribution System

The primary objective of this report is to develop insights and simplified procedures for assessing the ability of Distributed Generation (DG) facilities to continue in operation when subjected to temporary disturbances such as network faults. The scope is limited to stability considerations, described here to mean rotor angle stability for synchronous machine based DG facilities and speed stability for induction machine based DG facilities. DG facilities relying on power converter interfaces

4103: Powerline Vegetation Management Best Practices within Boreal Forest Caribou Regions

Caribou face threats from several sources, including habitat loss or alteration (including sensory disturbance), vehicle collisions, predation, and hunting. Powerline Rights-of-Way (RoWs), along with other linear features built through caribou ranges, contribute to these threats directly (e.g., direct habitat loss from RoW construction) or indirectly (e.g., increased predation pressure from wolves in caribou habitat along RoWs).The objective of this document is to define powerline vegetation man

3047: Common Spare Substation Equipment & Apparatus Database: User's Manual

The LCMSEA Common Spare Substation Equipment & Apparatus Database was developed as a web-based interface to facilitate the sharing of spare equipment between participating LCMSEA utilities.Participating LCMSEA utilities populate this database with information about available spare equipment including transformers, bushings, CTs, PTs, arresters, circuit breakers, disconnect switches, air compressors, relays, etc., and their contact information is associated with each entry. If a utility needs a p

33138: White Paper on Resiliency

The significant disruptions to power systems in recent extreme events make it timely to investigate what resiliency against such events really means, what is the value of resiliency, and what would be required to ensure that an adequate level of resiliency is provided – including, from the important perspective of transmission line systems. As such, this White Paper first presents a widely accepted and adopted definition of power system resiliency for the electricity sector and transmission line

3911: End of Useful Life Assessment Guide for RTU/Control Systems

In this project, an end-of-life (EOL) assessment guide and methodology were proposed to determine whether a control system was reaching its end of useful life. The focus of the project was on the major remote terminal units (RTU) and control devices and their connection and wiring peripherals.Asset degradation curves were presented for different types of devices in RTU systems, based on industry practice and utilities’ historic removal and replacement records. The developed

3364: Conductor Fatigue Work for ARMOR-GRIP® Suspension Clamps

This test program was initiated to determine the comparative Aeolian vibration fatigue performance of a conductor installed in an ARMOR-GRIP Suspension (AGS) clamp versus a bolted suspension clamp. To establish the fatigue performance of the AGS compared to a bolted suspension clamp, the conductor/clamp system was tested at one dynamic level. The antinode loop velocity was used as the control for the first test. To completely define the fatigue endurance characteristics between the two clamp sys

3241: Data Acquisition and Monitoring of Transmission Lines with High Resolution Satellite Images

A pilot project of the potential applications of WorldView-2 (WV-2) satellite imagery was carried out in a test area approximately 20 km north of Atlanta, Georgia, USA, for the benefit of the electric utility industry to validate the potential of using the technology in transmission line asset management operations. The project focused on six specific activities: visual asset inspection, vegetation management, damage assessment, GIS data capture and record validation, transmission expansion and

3382: Estimation of Safe Design Tension for TW (Compact) ACSR Conductors to Safeguard against Aeolian Vibrations

One of the objectives of this project is to investigate and develop recommendations for safe design tension of single, undamped, trapezoidal-wire (compact) ACSR conductors with respect to Aeolian vibrations. It is done by means of a mathematical model fed with specific empirical data regarding trap-wire conductor self-damping and fatigue endurance characteristics. The possibility to extend those recommendations to twisted-pair (T2 or VR) conductors is explored in the report. Another objective is
