Dissolved gas analysis (DGA) in transformers is a very successful periodic screening method to identify transformers that may be having problems. It is a symptom-based assessment of health, rather than a condition-based assessment. That is because the gases themselves do not cause failure, but are...
By Leon White and Traci Hopkins, H2scan Corporation As distributed generation, electric vehicle load, and requirements for increased electricity reliability provide real-world challenges for electric utilities, asset managers must innovate to ensure their infrastructure is in good condition to...
The evolving demands of modern power grids necessitate the adoption of advanced technologies that can provide enhanced efficiency, reliability, and flexibility. Smart transformers are at the forefront of this technological revolution, offering a range of capabilities that significantly improve the...
ABSTRACTHere we discuss the phenomenon of transformer inrush; what it is and its significance to transformer protection design. INTRODUCTIONA couple of years ago in this Transformer Special Edition, we wrote an article that covered the most used transformer protection schemes. As was pointed out...
The Growing Need for Safer and Greener Transformer Oils Transformer oil plays a vital role in the operation and longevity of power transformers, providing insulation, cooling, and arc suppression. Traditionally, mineral oil has been the industry standard due to its effective dielectric properties...
The Growing Concern of Transformer Fire Risks An Electrical Substation Transformer is a critical component of modern substations, playing a vital role in the transmission and distribution of electricity. However, due to the high-voltage operations, flammable insulation materials, and exposure...
The Growing Transformer Supply Crisis The global transformer supply chain is facing unprecedented challenges, with utilities worldwide struggling to procure essential equipment due to material shortages, manufacturing delays, and logistical constraints. Transformers are the backbone of electrical...
Power transformers are critical assets in electrical transmission and distribution networks. Their failure can lead to widespread outages, costly downtime, and potential safety hazards. As transformers age and operate under varying electrical and environmental stresses, degradation becomes...
