Abstract

Nowadays, distribution companies are requested to prepare detailed contingency plans, to efficiently manage temporary grid unavailability in case of a transformer failure. The main strategy to meet these challenges is to use adaptable recovery transformers with regards to compact, fast recovery and multi-voltage solutions — showing proven reliability under most demanding emergency conditions. This is the latest trend today after some years of development in materials, OEMs design rules and close collaboration with end users.The use of fast recovery adaptable transformers can significantly reduce reaction time — i.e., a compact single phase unit can be shipped and put into operation in just a few days. It would take weeks or even months to mobilize a large spare standard three phase transformer. The use of the right transformer technology, together with the use of high temperature material (as per IEC 60076-14), will allow to obtain reduced dimensions for such shipping activities. In this particular paper, a real case for a recovery shell-form adaptable transformer for renewable generation, having semi-hybrid insulation system, will be discussed. Both, compact shell and core form technologies are used for fast recovery applications. Selection of a design depends on the particular application, transportation limits and existing substation space limitations.
