Synchronous compensators are __________
(a) overexcited synchronous motor with no mechanical load
(b) overexcited synchronous motor with mechanical load
(c) underexcited synchronous motor with no mechanical load
(d) normal excited synchronous motor with no mechanical load
This question was addressed to me in an online interview.
My doubt stems from Power Factor Control of Synchronous Machines in chapter Synchronous Machines of Electrical Machines
