|when i am going to take trail on a 3ph sq.i/m motor 5.5kw,
i observed that RPM of the motor is very low as compared to
the rated RPM and also it rotates in clockwise in first ON
command,and anticlock wise in second ON command.
finally i observed that on phase is no available .
but iam not clear about, why the motor is rotates in both
directions without any phase interchanging.pls answer to my

|1.Whats the use of GNAC(Generator Neutral Accessory
2. why generator or any other system require Neutral
Grounding and not Phase grounding
3. what happens if any one of the phase is grounded.
4. if 15kv is grounded directly what will happen, why it
should not be grounded like that
5. use of of NGTR(Neutral Grounding Transformer and
Resistor) for grounding is helpfull and how
|When we use a multimeter, while checking continuity of a
closed circuit , what is happening inside multimeter, how
it is working to produce a beep wheather it is closed or
open.. is there any internaly voltage/current source

|We operate a 10 Mw facility and we have been experiencing
several trips due to fluctuations on the MVAR? We have
checked all issues related to the AVR and we have found all
OK? Can anyone help us? The grid voltage, internal voltage,
all regular parameters look ok. MVAR fluctuate and there it
goes the unit? What could be happening? Thanks!
