This collaboration between Enel and Hitachi ABB Power Grids will start in Italy, where Enel distributes around 200 TWh units of electricity to more than 30 million end-users. The pilot phase of the project will take place in Enel’s substation of Cortina D’Ampezzo using two 40 MVA TXpertTM digital power transformers. This will increase reliability of the electrical grid in the well-known mountain resort of Cortina, situated in the heart of the southern Alps in Veneto region of Northern Italy.
First hosting the Winter Olympics in 1956, Cortina has been home to several world-famous winter sports events. It will host the FIS Alpine World Ski Championships in 2021 and the Winter Olympics for a second time in 2026. Substation operators in Cortina habitually face challenging weather conditions such as heavy snowstorms in winter - and they have recently been contending with the COVID-19 pandemic. Deploying service workers to regularly check transformer health is expensive and may not always be possible due to the harsh weather conditions, something made easier by the digital power transformers technology.
How are digital transformer technologies revolutionizing the power industry?
Research published by CIGRÉ(1), a leading, global nonprofit organization in the field of high-voltage electricity, found the benefits of transformer monitoring has the potential to deliver 75% reduction in repair costs due to early detection, a 60% reduction in revenue loss due to unanticipated, problems or outages, a 50% reduction in risk of catastrophic failures and annual cost savings up to 2% of the price of a new transformer.
TXpertTM enables a data-backed, scientific approach for measuring transformer aging and performing analytics on transformer health.
“With TXpertTM we will optimize the operations and maintenance of our transformers. We expect to improve reliability and reduce risk with consequent life extension of transformers, looking at the company targets of a more sustainable grid and better power quality,” said Flavio Mauri, from Enel’s Infrastructure and Networks division. “Together with Hitachi ABB Power Grids we will create value by deploying intelligent solutions for the main components of electricity networks”.
As per another recent CIGRE report (2), the top three locations of faults in transformers are windings, tap-changers and bushings. Our TXpert™ Ecosystem mitigates all of these and in the future will enable the customer to implement remote and advanced services which can provide virtual site management and life assessments.
