Scope

Scope 1 of IEC 61869-1:2023 applies with the following addition:

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 400 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 series. 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 5J.501 and 5J.502.
