Non-standard methods of current and voltage measurements
 Talába, Michal ; Boušek, Jaroslav (referee) ; Hubálek, Jaromír (advisor)
This work brings a study about non-conventional methods of voltage and current measurement, followed by a creation of magneto-resistive material based current sensor prototype, suitable for medium voltage switchgear from ABB. Outcome of the study is description of physical principle and the measurement principle of non-conventional methods. Outcome of the experimental part is a current sensor based on magneto-resistive component, which can measure magnetic field generated around a wire with flowing primary current. Through the magnetic field, the sensor can measure primary current flowing in the wire. Sensor was measured in range 0 – 1000 A, and its accuracy and linearity was approximately 6%. The main contribution of this work is the confirmation that this non-conventional method works for measurement of high currents. Based on the outcome, ABB can decide whether is this technology suitable for its product portfolio.
