Zusammenfassung
The introduction of UHV systems mainly supplied by nuclear power stations will involve recourse to a new
generation of power transfonners. Jn choosing these units, account should be taken both of the needs of the
system and of the difficulties to be faced in manufacturing transfonners with advanced characteristics.
The Paper discusses the main ratings that step-up transfonners and interconnection autotransfonners should
have, and stresses the advisability of providing reserve units in nuclear power stations. The need for transfonner
units characterized by a high reliability is emphasized.
Experimental plants for research on the behaviour of transfonners should be provided well in advance of the
introduction of a UHV system as scheduled in the planning studies.
