| how to calculate load if i have three phase & single phase
connection from power transformer( in term of kw & kva).can
i take single phase load/3 for total kw calculation
| | 1 |
| how can we change the rotating direction of single phase AC
induction motors? | L&T | 5 |
| FOR TESTING 33KV CABLE HIPOT TESTING.HOW MUCH KV WE HAVE TO
APPLY .GIVE IN DETAILS. | | 11 |
| like the transformer another electrical static device which
operate on same priencipal? | Power-Grid | 8 |
| THE 40 MW OF POWER FOR 220 V III PHASE POWER CONNECTION
REQUIRES HOW MANY KVA POWEER REQUIREMENTS | Chartered-Accountant | 5 |
| WHAT IS THE REASON FOR LOW VOLTAGE IN HOUSES? | Maytas | 11 |
| what happens when a power transformer neutral earthing
broken??? | MacLellan | 3 |
| What are the types of circuit breakers ? | Genco | 1 |
| Initially motor starts with star connection ,after few
timing changes to delta connection, why the motor should
run continously in star connection,it gives high torque &
low current? | | 3 |
| why mccb is not tripping when phase & neutral terminal are
interched ? | | 3 |
| At site, we have 30Kw motor (3 phase, 400V,50Hz) and FLC
54A as per the nameplate. At the time of starting it draws
840A instead of 390A (7.2%). As per the data sheet also its
390A starting current. it thru a dol starter from the MCC.
can anyone tell what is the problem in the motor | | 2 |
| why star point of motor shall not be grounded? | | 5 |
| In a 11000/440 V transformer, when any one phase of 11 KV
supply fails (ie., single phasing), what happens to the
secondary voltage and why? | Secure-Meters | 2 |
| define transient state &steady state | | 1 |
| which have higher efficiency transformer or induction moter | BARC | 3 |
| One of the advantages of HRC fuse links is that they can be
used to back up equipment with an inadequate rupture
rating. briefly discuss what this means | | 1 |
| can we connect transformer with star conected secondary to
delta connected primary in series? | | 1 |
