CLC/TC 14 Power transformers

Harmonization Document

Scope

This standard is restricted to transformers having only one tapped winding - For auto-transformers this means that the number of turns per phase in either the high-voltage (H.V) or low-voltage (L.V) winding is constant (auto-transformers with tapped neutrals are subject to agreement) - Tap changing involving a phase displacement in the voltage is not taken into account
