If you work with high voltage equipment in any industry, it is important to have a basic idea of what partial discharge is and to know the steps you can take to arrest it at an early age.
To begin with, partial discharge (PD) is an electrical explosion that takes place in a localized area in the insulation system. It usually occurs between two conducting electrodes without completely sealing the gap. The process is harmful, especially if it goes undetected and reaches a level where it causes complete disruption of power.
As other people, you may wonder what actually causes partial discharge in high voltage electrical applications. Well, the process often takes place because of imperfections and discontinuities in the electrical flow. Once it starts, partial discharge can escalate into electrical trees and surface tracking, ultimately causing a total disruption in the entire system.
Based on the type of imperfection and discontinuity in the insulation system, it can take between a few hours and several years to notice a complete failure. It is also important to know that some types of discharges are dangerous, especially the ones that occur in polymeric cables and other cable accessories. On the other hand, some discharges can remain harmless such as corona that takes place in high voltage overhead networks.
To discover issues related to partial discharge in various high voltage applications, reliable partial discharge test equipment is necessary for effective partial discharge measurement. Professionals with adequate knowledge and experience in partial discharge testing should carry out this process to ensure proper diagnosis.
The goal of online PD testing is to determine if there is any disruption in the insulation system by conducting proper partial discharge analysis. The diagnostic testing also helps uncover the difference between various types of partial discharge that can take place in the system. Once detected, the best action to take is to notify a specialist from a certified company dealing with partial discharge testing and monitoring.
