Abstract

In this study, PIC 18F4520 based wye-delta starting
and protection relay was designed and manufactured with semiconductor devices for
three phase cage rotor induction motors. Protection relay controls the phase
absence and phase sequence before motor starting process. Designed relay system
performs better than that of other electromechanical starting and protection
relays, due to the decrease in the number of electromechanical components,
total volume of relay, complexity of system. Furthermore, the use of microcontroller
and semiconductor devices makes the new starter and protection relay design more
robust and more reliable.
