Voltage transformers
Applies to new voltage transformers for use with electricalmeasuring instruments and electrical protective devices atfrequencies from 15 Hz to 100 Hz.The general requirements apply to all voltage transformers, but,for certain types, e.g. capacitor voltage transformers, therequirements are subject to the modifications stated in theappropriate chapter. Although the requirements relate basically totransformers with separate windings, they are also applicable,where appropriate, to autotransformers. The standard does not applyto transformers for use in laboratories.The requirements for inductive voltage transformers are supersededby IEC 60044-2 (1997).

Instrument transformers - Part 5: Capacitor voltage transformers
This part of IEC 60044 applies to new single-phase capacitor voltage transformers connected between line and ground for system voltages Um 72,5 kV at power frequencies from 15 Hz to 100 Hz. They are intended to supply a low voltage for measurement, control and protective functions. The capacitor voltage transformer can be equipped with or without carrier-frequency accessories for power line carrier-frequency (PLC) application at carrier frequencies from 30 kHz to 500 kHz.
