Mobilizing transformers

The installations that deliver power to your home or factory are designed and maintained to provide the highest levels of reliability. However, despite good design and maintenance, failures can never be ruled out altogether. A severe incident can put a transformer out of service for months or even over a year while a replacement is procured or heavy repairs effected. To be able to serve customers in the interim, an alternative is needed. One solution is to deploy a mobile transformer. Such a transformer is sufficiently small and light to be able to be moved by road, either in one piece or in a way that permits rapid assembly and commencement of service. Until now, mobile transformers have been limited to 230 kV. Through innovative design, ABB has now been able to deliver a 400 kV mobile transformer.
