Medium-Voltage Cables

Scott Blizard, American Electrical Testing Company LLCColumns, Fall 2020 Columns, President's Desk

Welcome to the fall edition of NETA World. In this issue, our authors cover the various methods for performing testing on medium-voltage cables. I recommend you start with the article by Tom Sandri of Shermco Industries, which lays out the current test methods for acceptance and maintenance testing of medium-voltage cables. Next, dive into the articles on specific testing methods including partial discharge, dissipation factor (tan delta), and VLF.

Fall is typically one of our busiest times of the year. Many of our customers are performing scheduled maintenance outages, and the workdays can be longer as well as more stressful than normal. Even if your days throughout the fall season are not that much different, one thing we must constantly do is evaluate and mitigate exposures to risk. This helps make the work environment safer for all. When working with medium-voltage cables, be sure the technician has all the documentation as well as a clear understanding of the testing method and the test equipment being used to perform the testing. Review the safety precautions needed to operate the equipment or device and ensure all recommended safety precautions are followed.

Today is July 16, 2020, and the country is in the middle of a COVID-19 resurgence. NETA Member Companies and their technicians throughout the United States and in Canada have been identified as essential workers as they support and maintain the critical infrastructure of our nations. Follow the COVID-19 policies of your company as well as your customers’ companies. The preventative measures to limit the spread of the COVID-19 virus that have been communicated by the CDC in the United States and the Public Health Agency of Canada should be included. Be safe, and err on the side of caution.

Mark your calendars! PowerTest 2021, the premier electrical maintenance and safety conference, will take place March 8–12, 2021, at the Rosen Shingle Creek in Orlando, Florida.  We look forward to seeing you there.

Coach safe behavior…Living injury and disease free every day!
