Answer / v.selvakumar

if suddenly remove field from generator it will take
rective power from infinite bus ,but it will continuously
supplies active power ,that means it act as induction
generator.

Answer / ashwin.k

when supply 2 field is removed......then stator winding(in
higher rated m/c)is subjected to bus bar volage of infinite
bus.....thus alternator acts as INDUCTION MOTOR....amazing naaa

Answer / niranajn

when the field is removed the alternator will act as an
induction motor

could mail me the question papers for the test.

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
