Obtaining real-time operating data on power plant and substation equipment has never been easier. The sensors, transmitters, and systems needed to monitor important parameters are readily available and highly cost-effective. The ability to identify problems early and make repairs prior to catastrophic failure improves system reliability and saves utilities money.
To get the best from your bushing monitor, it is vital to set expectations up at the outset and ensure the monitor, its maintenance and management are included in the asset management plans of the organization. Then we can expect to get sensible data which can be used to both detect bushing deterioration and subsequently support bushing investigation and diagnostics.
This article by Doble’s Dr. Tony McGrail in Transformers Magazine explores the intricacies of DGA monitor accuracy, emphasizing the challenges in extracting dissolved gases from transformer oil. Despite international standards like IEC 60567 recommending a maximum accuracy of 15% for complete DGA systems, real-world application, as reflected in CIGRE brochures, suggests a potential deviation closer to 50%. The implications of varying accuracies on diagnoses, particularly when employing diagnostic tools like the Duval triangle, are analyzed.

Matters of NERC PRC and NERC CIP compliance intersect during protection system testing on substation networks. In the modern regulatory environment, the benefits of computer-based relaying are challenged by the costs of cyber security and disrupted or insufficient relay testing practices. The way forward demands interconnected data and the ability to track critical metrics automatically. Organizations can modernize while ensuring compliance readiness by implementing systems that integrate protection and cyber domains into scalable management platforms.
When primary station equipment trips out, it is often the substation maintenance engineers who must review the situation, get the data needed to make an informed decision, and then ‘make the call’…
