Introduction
EN 50588-1:2017, 10.1.3 states that a medium power transformer could have different termination
features.
The following constructional situations are possible.
i) Termination in open type (oil-air) bushings without protection. This is covered by EN 50588-1,
EN 50180, EN 50386 and EN 50387.
ii) Termination in plug-in type bushings of inside or outside cone type. This is covered by EN 50588-1
and EN 50180.
iii) Termination in air filled or compound filled cable boxes or protective enclosure using open type
and/or oil/compound oil-oil bushings, as defined in EN 50588-3.
iv) Flange boxes and similar solutions using open type bushings can also be used.
