Instrument transformers - Additional requirements for capacitor voltage transformers Ingestion-build-68772 Guidance for testing ECS is1 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
