Consider the following statements:
In a 3-phase induction motor connected to a 3-phase supply; if one of the lines suddenly gets disconnected, then the
1. Motor will come to a standstill
2. Motor will continue to run at the same speed with line current unchanged
3. Motor will continue to run at a slightly speed with increase in the line current
4. Rotor current will have both of sf and (2-s)f component frequencies where s is the slip and f is the supply frequency
Of these statements:
(a) 1 and 4 are correct
(b) 1 and 2 are correct
(c) 3 and 4 are correct
(d) 2 and 3 are correct
