An investigation of a three-phase measuring transducer of active current based on a transformer reactor

Abstract

The design and operating principle of an active-current three-phase measuring transducer based on differentiating induction-current transducers without using integrated filters are considered. The dependence of the measurement accuracy of the active component of load current of a synchronous generator on the value of EMF of a differential induction-current transducer is determined. A scheme of computer simulation of a three-phase measuring transducer of active current is described. The results of computer simulation and experimental studies of the device confirming the ability of the transducer under consideration to replace the traditional solutions based on current transformers for marine electric-power systems are presented.
