|how can i select the cable ratings
|What is the difference between Contactor and Circuit
|IN WHICH MODE THE TRANSFORMER WILL GET A MAXIMUM OUT PUT
VOLTAGE. ASKED FOR POWER GRID EXAMINATION
|CAN A CD/CLOCK RADIO WITH 110V 60HZ WORK ON A 110V 50HZ
|We have a 33/11kv switchyard having 12.5 MVA power
transformer. We export & import power through this
transformer. When we export power, the PF will be depend on
GRID PF & when we import power the PF will be depend on our
load PF. but the problem is that,when neither we export nor
import but our 33KV vCB is in close position,our meter read
the power factor 0.14 to 0.25 at that moment. So how can be
we improve the power factor at that moment.
|why should we connect the no load components in a
equivalent circuit of transformer in parallel?why cant it
be in series.
|Which is the best protection in case of shortcircut fuses or mccb ?
|What are the different types of circuit breakers?
|what are the methods of speed control of dc motor???
|In case of 3Phase Supply,
Voltage R-Earth/Neutral - 220
Y-Earth/Neutral - 220
Z-Earth/Neutral - 220
Total is -> 660Volts
Then Why it is said that 3Phase supply is 440
|For 300MW and over a distance 250 km, what voltage be
selected? and no. of circuit?
|How to connect surge arrester with equipment?
