what is conductor constant taken for calculation of voltage regulation of 11 kv and 33kv line on dog aor rabbit conductor
CSPDCL-Chhattisgarh State Power Distribution Company Limited,
1 17841which transfofrmer oil break down voltage strength get will be more if oil sample taken from bottom of tank or oil sample taken from top of the transfomer tank.
2 5262can any one tell me about the Extra low voltage systems?From where we give supply to these type of systems??
MCB,
1857Generally we denote power in 'p',voltage in 'v'but why can't we denote current in 'c' instead of I.
Bhel,
4 11308A transformer has negative voltage regulation when its load PF is A zero B unity C lagging D leading
1 8081If we impress a dc voltage of 230 V on an unloaded 230 V, 50 Hz transformer it wi A give high secondary voltage B burn out C give secondary voltage as per K D none of these
1959If we impress a dc voltage of 230 V on an unloaded 230 V, 50 Hz transformer it wi A give high secondary voltage B burn out C give secondary voltage as per K D none of these
1 3173Short circuit voltage of a transformer mainly depend on A ohmic resistance of primary B ohmic resistance of secondary C magnitude of leakage flux D cross sectional area of core
1 9518Resistance of low voltage side of transformer compared to high voltage side is A less B equal C more D depens on design
1 5613In 3 phase induction motor even with low Voltage it reaches nearly it's rated speed why? (for example instead of 400V it reaches with 250V)
2 4601In a voltage-controlled current source A A current booster is never used B The load is always floated C A stiff current source drives the load D The load current equals Isc

How does a Bandgap Voltage reference work?
How about voltage source?
How do you size NMOS and PMOS transistors to increase the threshold voltage?
Explain the basic circuits for a current- and voltage- clamp set-up.
What types of I/O have you designed? What were their size? Speed? Configuration? Voltage requirements?
I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
iam using DM 3251 voltmeter(1 percent accuracy)for 11KV system PT ratio is 11KV/110V.can anybody explain what is the max and min voltage deviation.
how define the torque in ac drive. from electrical side in the drive friquency ,voltage and current three factor is there.
can we calculate the voltage level for microwave energy which is using for our mobile communication?
Is it possible to calculate a voltage for microwave energy generating in oven? Is there any formula relating frequency and voltage and it should be independent of speed?
