Scope

This European Standard gives particular requirements for voltage transformers used in a.c. single-phase railway applications, fixed installations.
This European standard refers to single-phase inductive voltage transformers for railway applications on 15 kV, 16  Hz and 25 kV, 50 Hz overhead lines, these voltages and frequencies being defined in accordance with EN 50163.
The main uses of these voltage transformers are:
 voltage indication;
 measurement;
 protection.
