This paper advocates the use of active current and potential transducers for proper utilisation of fast protective relays. The active current transducer faithfully transforms the primary current containing a slowly decaying d.c. component, thereby providing a good transient response. The active potential transducer helps in fast extinction of ferroresonance oscillations. Results oflaboratory investigations are also presented.
