FREQUENCY RESPONSE OF SELECTED CURRENT TRANSFORMES AND HALL-EFFECT CURRENT SENSORS

• Abstract:

  This paper is dealing with the comparison of isolated current sensors of nominal value up to 200 A. Emphasis is placed on the operation of the sensors at very low frequencies, where the amplitude and phase error is evaluated. This research was needed for the choice of an optimal current sensor for the development of a diagnostic system for induction motors. The most suitable sensors in the terms of performance and cost are selected in accordance with the application.
