Abstract
Diplomsko delo opisuje tuljavo Rogowski in njeno uporabo v elektrotehniki. Tuljava Rogowski je izdelana na tiskanem vezju. Z izvedbo na štiri plastnem vezju sem dosegel, da je bila gostota navitja na dolžinsko enoto pri vnaprej določenih dimenzijah čim večja, istočasno pa je bila izvedena tudi povratna vez na notranjih slojih vezja. S tem sem se izognil kompleksnemu združevanju več tiskanih vezij in tudi dosegel kompaktnejšo izdelavo, s prigraditvijo integratorja pa zagotovil izhodni signal, ki je premo sorazmeren merjenemu toku. Glede na to, da sem se omejil na izdelavo tuljave Rogowski in prigradnjo integratorja, menim, da bi se s podrobnejšo nadaljnjo raziskavo lahko izboljšala občutljivost in točnost, saj so izmerjene vrednosti z mojo napravo odstopale od izmerjenih preko kontrolnih tokovnih klešč.

Title:Rogowski coil in PCB form
Abstract:
The thesis describes a Rogowski coil and its use in electrical engineering. Rogowski coil described here is constructed on a printed circuit board. By using the four layer PCB, I achieved optimal number of windings for physical dimensions determined by the design, where return line is routed through a middle layer of the PCB. With this construction I avoided any complicated assembly with multiple PCBs. With introduction of the integrator, I have ensured that output signal corresponds to measured current. Given that this thesis is restricted on construction and manufacturing of the Rogowski coil and integrator circuit, and the fact that values I obtained with this construction differ from values obtained by using calibrated commercial current sensing probe, I think that with further development, sensitivity and accuracy can be increased.

Keywords:alternating current, Rogowski coil, printed circuit board, integrator, operational amplifier, frequency.
