    Abstract - (Show below) - (Hide below)

    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.
