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’…
As an integral part of the electric delivery system around the world and the interface between the transformer and overhead bus, bushings failures have a significant negative impact. Because of this, there is a special focus on determining the root cause of the failure. A bushing teardown investigation is employed in cases where there is a need to determine the failure mechanism. This paper is a brief synopsis of how companies perform a bushing teardown.
The design life of a transformer is usually about 20 to 25 years. In the United States, estimates show the average age of a transformer is currently around 42 years, which means a number of even older units are still in service. As with all things, transformers age and degrade over time. Transformer failures can come from a variety of sources including through faults, faulty crimps and brazes, corrosive sulfur, poor design, water intrusion, collateral damage from a bushing or load tap changer (LTC) failure, incorrectly sized leads, and a host of other issues. Overall, however, the demise of a transformer from normal aging is linked directly to the condition of the solid insulation (i.e. paper, cellulose).
We should have expectations when applying condition monitoring to transformers. If we know what to expect then we can identify measurements which are unexpected or anomalous and worthy of deeper investigation.
