Measurement current transformer vs. protection current transformer. Whilst measurement current transformers are intended to reach saturation point as quickly as possible once they exceed their operational current range (expressed by the overcurrent factor FS) – in order to avoid an increase in the secondary current with a fault (e.g. short circuit) and to protect the connected devices.

  • Learn How To Specify Current Transformers | EEP

    Aug 19, 2020Current transformers are used to supply information to the protective relays and/or current, power and energy metering “instruments”. For this purpose they must supply a secondary current proportional to the primary current flowing through them and must be adapted to network characteristics: voltage, frequency and current.

    Feb 01, 2016The schematic diagram of a power transformer is illustrated in Fig. 1 with the vector group YNd11. Since the currents at the transformer low voltage (LV)-side lag those of the high voltage (HV)-side by 30&, the current phase-shift due to the YNd vector group should be compensated to calculate the differential current.
