In the world of electrical utilities, the growing demand for power, aging infrastructure, and overloading of grids lead to an increasing number of failures. These issues disrupt the continuity of electricity supply, cause unexpected outages, and lead to significant financial losses.
One of the significant yet largely invisible threats to power systems is corona partial discharge (Corona PD). Corona PD is both an indicator of malfunction and an active destructive factor that should be eliminated. Over time, the discharges cause damage to the electrical components, eventually leading to system failures.
Detecting corona PD early is crucial to ensure the health of the power system. Accurate and timely detection allows for proactive identification and rectification of potential equipment failures, thus preventing costly, disruptive power outages.
The Precision of Pinpointing: In detecting corona discharges, precisely locating the origin of PD is essential. Accurate localization aids in assessing a fault’s severity and distinguishing between multiple co-existing faults. This differentiation is vital for targeted maintenance efforts.
