Resumen:

This part of IEC 61869 applies to new single-phase capacitor voltage transformers connected between line and ground for system voltages U m = 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.
