The market has seen new vacuum-based switching devices (reclosers or circuit breakers) that offer several advantages on Medium Voltage distribution networks. These new devices brought new challenges when performing timing tests in the field.

 

Join this webinar to learn about the new technologies and test instruments that will help you overcome those challenges and get timing measurements safely and efficiently

Testing Tactics:

Test Methods & Data Analysis of Offline PD Measurements on Power Cables

10 a.m. CT Friday, June 17

Power cable infrastructure is the backbone of power transmission and distribution systems. In many cases, these cables have been in service for 20 years or more. The influence of stress factors, such as water ingress, mechanical damage, electrical stress and imperfections created during manufacturing or installation all contribute to decrease cable life.  Evaluating and trending cable integrity over time is essential to improving the reliability of power transmission and distribution systems.  Partial discharge testing is an essential technique used for this evaluation and data collection.

 

Partial discharge is a non-destructive testing method that allows the end user to determine the overall cable health without impacting the life of a cable. PD measurements should be included as a part of a cable testing maintenance program to monitor the integrity of a cable system. The diagnostic information gained from these measurements will help to determine if further steps are necessary to repair or replace a cable before it fails while in service. This can significantly reduce the damage and lost operation time that may occur due to an outage resulting from an unexpected cable failure. 

 

This webinar will include power cable fundamentals, common failure conditions, the importance of a maintenance program, partial diagnostic methods, testing standards, and test data analysis. It will focus on the partial discharge testing practices and how applying the test results can increase cable network reliability. This will include the available wave forms, test setup, common cable connection types, pass/fail criteria and creating a report.
