Introduction

This part of the EN 50708 series deals with the energy performance of non-conventional technology

Medium Power Transformers.
For the purpose of this document, the requirements of EN 50708-1-1 apply.

This document contains particular requirements for specific transformers or transformer applications,

which are based on the requirements of EN 50708-1-1.

This document should be considered in conjunction with the requirements of the general parts.

The particular requirements of the different sub parts of EN 50708 supplement, modify or replace

certain requirements of the general parts of EN 50708-1 and/or EN 50708-1-X being valid at the time

of publication of this document. The absence of references to the exclusion of a part or a clause of a

general part means that the corresponding clauses of the general part are applicable (undated

reference).
