The purpose of this standard is to determine the electrical and design characteristics that are not included in UNE-EN 50588-1, or for which several options are established in the standard and that are of general use in the distribution electrical Spanish systems.This document covers power transformers assigned from 25 kVA to 3 150 kVA intended for operation in three-phase distribution networks, for continuous operation indoors or outdoors, 50 Hz, immersed in dielectric liquid, natural cooling, with two windings:- A primary winding (high voltage) with two voltages assigned and with highest voltage for equipment from 3.6 kV to 36 kV.- A secondary (low voltage) winding with a highest voltage for equipment not exceeding 1.1 kV.For that issues that are not addressed in this standard, UNE EN 50588-1 and UNE 21428-1 are applicable.
