CSA Preface

This is the first edition of CAN/CSA-C61869-5, Instrument transformers — Part 5: Additional requirements for capacitor voltage transformers, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61869-5 (first edition, 2011-07). Together with CAN/CSA-C61869-1, it replaces CAN/CSA-C60044-5, Instrument transformers — Part 5: Capacitor voltage transformers, which was published in 2007.

For brevity, this Standard will be referred to as CAN/CSA-C61869-5 throughout.

This Standard is part of the C61869 series of Standards on instrument transformers, which consists of adoptions with Canadian deviations of the IEC 61869 series of Standards. The IEC 61869 series restructures and updates the previous IEC 60044 series of Standards. Requirements common to a variety of instrument transformer types are grouped in CAN/CSA-C61869-1; the remaining Standards in the series state requirements for specific types of instrument transformers.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

This part of IEC 61869 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.

The base requirements for coupling capacitors and capacitors dividers are defined in IEC 60358. The transmission requirements for coupling devices for power line carrier (PLC) system are defined in IEC 60481.

The measurement application includes both indication measuring and revenue measuring.

NOTE 501 Diagrams of capacitor voltage transformer to which this standard applies are given in Figures 5A.1 and 5A.2.
