WESTERN AREA POWER ADMINISTRATION

PERFORMANCE WORK STATEMENT (PWS)

Corona Infrared Scanning

January 2022

1. REQUIREMENT OVERVIEW

1.1. Scope

The Western Area Power Administration (WAPA), Sierra Nevada Region (SNR) requires a Contractor to scan several high voltage electrical transmission lines for Corona and arcing. The camera equipment used will record Ultra-Violet (UV) video images and Infra-Red (IR) images.

High definition still pictures of areas with corona are required. The data will be reviewed and analyzed. Reports will be generated showing all areas of concern and their order of severity so that maintenance can be prioritized. SNR has approximately 1,280 miles of transmissions lines and 6,953 structures. For detailed breakdown of all SNR transmission lines, see Attachment 1 -

WAPA_SNR_All_Lines_Structures.xls

1.2. Background

WAPA, part of the U.S. Department of Energy (DOE), is a Federal power marketing administration that markets and delivers reliable, cost-based hydroelectric power and related services. SNR serves customers in California and Nevada. SNR’s mission includes maintenance and operation of the high-voltage transmission system, including substations and high-voltage power transmission lines, ranging from 4.16kV to 500kV, which deliver power to its customers.

Most of the transmission lines are on steel towers and use both porcelain and polymer type insulators to attach the conductor to the tower. The transmission lines are three phase and have one conductor per phase except for the 500kV transmission lines which have multiple conductors per phase and use spacer dampers between towers to hold the multiple conductors in place.

Over the last 33 years, SNR has experienced one polymer insulator failure, several porcelain insulator failures caused by lightning strikes, and numerous spacer damper failures. Some of the transmission lines are over 50 years old and there is concern over the electrical and mechanical integrity of the insulators and spacer dampers. In recent years there has been a lot of attention given to the risks of faults in the transmission system initiating wildfires. As a result of this concern, SNR is increasing its use of corona, UV, and IR scanning of all its transmission lines. As part of this analysis SNR requires a corona discharge UV and IR evaluation performed on large portions of its transmission line facilities to determine whether there are any electrical and/or mechanical problem areas that need further evaluation and/or replacement.
