IEC 60044-5-2004 Instrument transformers. Part 5: Capacitor voltage transformers

Language: English, French
International Standard IEC 60044-5, has been prepared by IEC technical committee 38: Instrument transformers.
This standard replaces IEC 60186 regarding capacitor voltage transformers as well as IECPAS 60044-5.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
Scope
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.
This standard replaces IEC 60186 regarding capacitor voltage transformers.
Three standards formed the basis for this IEC 60044-5 standard:
• IEC 60044-2, concerning inductive voltage transformers;
• IEC 60358, concerning coupling capacitors and capacitor dividers;
• IEC 60481, concerning coupling devices for power line carrier (PLC) systems.
The measurement application includes both indication measuring and revenue measuring.
NOTE Diagrams of capacitor voltage transformer to which this standard applies are given in Figures A.1 and A.2.
