21-36 PROIECTAREA SESIZORULUI CAPACITIV DE ÎNTRERUPERE A UNEI FAZE, A SISTEMULUI TRIFAZAT DE ALIMENTARE CU ENERGIE A MOTOARELOR ELECTRICE


DESIGN OF CAPACITIVE SESIZORULUI
CANCELLATION OF A THREE-PHASE SYSTEM,
THE POWER OF ELECTRIC MOTORS
In this paper presents the design of capacitive sensor used for phase
brake of a three phase system, for electronic protection relay of three-phase
induction motors. The electronic protection depends on the load current
amplitude, which does not allow starting the motor in two phases.
