Measurement of elektrical and nonelectrical quantities of motor drive for switchgear
Pěček, Dominik ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
Bachelor’s thesis deals with measurement of electrical and non-electrical quantities on motor drive MP-BD-X230. As an introduction the classification of drives for switchgear is analysed and circuit breaker BD250 is described. Thesis continues by explaining application, basic nature and design solution of motor drive MP-BD-X230. Another step is description of workplace and devices which will be used for measurement. Measurement procedure of electrical and non-electrical quantities is also carried out accompanied by evaluation of measurement. Final part of the work deals with calculation of uncertainty of measurements with a reference to each individual measurement calculation and also deals with determination of measurement errors.
