Customer’s challenges and solutions When we address the topic of electrification, there is a strong social and economic commitment to supply high quality energy and build a strong and reliable power grid to help all humanity. In reality, almost 700 million people do not have access to electricity today and about the same number are expected to remain in darkness by the year 2030 (IEA). In this progressive challenge towards a more economical, dependable, and environmentallyfriendly energy supply, transformers play a fundamental role. The invention of the transformer was the key to unlocking energy...

Industrials Downstream from the transmission, we reach the distribution network where the load becomes more variable, and stability of the system is paramount. Voltage regulation is imperative to manage the load and work efficiently. However, distribution networks are quite busy and the process of isolating a transformer may not be as easy as many would think. Oil sampling is always a safe and practical decision to estimate the most important condition of the insulation system inside the transformer without the need of disconnecting it from service. Oil testing can be performed on transformers...

Having a good understanding of potential failure locations and failure modes means that it is expected that necessary preventative and proactive maintenance practices will be taken to minimise the risk of power and distribution transformer failures. Transformer asset managers base their decisions on accurate information obtained from off-line testing and on-line monitoring devices. Good assessment and decision making is a result of reliable instruments gathering accurate test data that can later evaluate the electro mechanical and dielectric condition of a transformer during its service life....

Bringing electric energy into the transformer is achieved by using bushings. They are able to conduct electric energy and isolate the energy from exposed areas. The insulation of high voltage bushings (RBP, OIP, RIP, or RIS) is divided in to different insulation media (oil-to-air, oil-to-gas, and oil-to-oil). This enabled them to be used outdoors or indoors, depending on the application. Transformer winding design and assembly is one of the most significant steps in transformer construction and future reliable operation. The number of turns in the winding defines the ratio of voltage and current...
