Electrical systems are the backbone of modern infrastructure, powering everything from homes and businesses to industrial facilities. However, the reliability of these systems can be compromised by failures resulting from wear and tear, environmental factors, or improper maintenance. Diagnosing electrical system failures accurately and efficiently has become increasingly important to ensure safety, minimise downtime, and avoid costly repairs. Techniques such as Partial Discharge Testing have emerged as crucial tools in identifying and addressing potential faults in electrical systems. These advances, along with innovative technologies and methodologies, are revolutionising the way we maintain and troubleshoot electrical systems. This article explores key…
