A partial revision of AS 1243-1982 by means of adoption of IEC/PAS 60044-5:2002 to specify requirements and tests for capacitor voltage transformers.

Scope

This PAS which is a part of International Standard IEC 60044 applies to new single-phase
capacitor voltage transformers connected between line and ground for system voltages Um ¡Ý 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.
The future standard that should supersede the present PAS will replace the IEC 60186 regarding capacitor voltage transformers.
Three standards formed the basis for this IEC-PAS 60044-5:
−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 application measurement function includes both indication measuring and revenue measuring.
NOTE Diagrams of capacitor voltage transformer to which this document applies are given in figures A.1 and A.2.
