适用范围

This Standard 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. This standard replaces GSO /IEC 60044-1:2007 regarding capacitor voltage transformers. Three standards formed the basis for this standard:  The Standard (1), concerning inductive voltage transformers;  The Standard (2), concerning coupling capacitors and capacitor dividers;  The Standard(3), concerning coupling devices for power line carrier (PLC) systems. The measurement application includes both indication measuring and revenue measuring. NOTE Diagrams of capacitor voltage transformer to which this standard applies are given in Figures A.1 and A.2.
