What is the relation of the ratio of rotor current limits and the ratio of lower limit to upper limit current?
(a) ratio of rotor current limits = ratio of lower limit to upper limit current
(b) ratio of rotor current limits > ratio of lower limit to upper limit current
(c) ratio of rotor current limits < ratio of lower limit to upper limit current
(d) no relation between ratio of rotor current limits and ratio of lower limit to upper limit current
I got this question in an international level competition.
I want to ask this question from Motor Starters, Calculation of Resistance Steps & Design of Field Regulators topic in division Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
