Will transformer heating be approximately the same for resistive, inductive or capacitive loads of the same VA rating? Explain.1 11458
in a dc shunt motor what happens if motor takes high current,no speed2 3708
what is meant by armature reaction & where its happen ?3 5417
Regarding units, for voltage we are denoting Volts as V but in case of current we are not denoting Ampere as A instead as I..Why..? Any technical reason for this..?1 3444
how DC motor operating in detail .pls any one guide me .iam not clear idea about that .thank u2 3700
what is the difference between squirrel cage & slip ring induction motor?17 81781
Size of the power cable like 1.5,2.5,4 sq.mm which area calculated from whick area or how specified the size?
why distribution transformer is uesd in Delta/Star formation?is there any significance in doing this?If yes then breif?3 8179
why generation is done in delta nad transmission in star? brief3 8348
Why phase sequence must be same in any ht motor or generator circuit?if phase sequence doesn't same whatever will be affect on circuit?
how to control the speed to switched reluctance motor
what happens if dc supply is given and the remedies for it.
How to design a Unit auxiliary transformer for a power house having a unit of 65 MW and Generating voltage of 11 KV and Secondary voltage of 433V
What is the formula to calculate the no load current of a single & three phase induction motor
Why do we mostly prefer to generate and distribute electricity in 3 phase and not in 4 phase or 5 phase?
how much winding resistance of 0.75kw to 12.5kw 3ph sqwiralcage induction motor?
What is the function of attenuator in cro?
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
Why does increasing the magnetic flux in the main field of a d.c motor cause the armature current to reduce??
How is the connection of the tap changer on the HV side been made?
For RCD (Residual current device) Icu is defined. How i can find Ics for them?
I am getting above 60 V as open delta voltage against single phase unit ICT at tertiary delta formed and ICT getting trippped on NDR. ICT tested and found in order. PTs provided on tertiary are tested and in order. what may be the reason?
132/66kv sub-station procation ?
can we start slipring motor on star delta like we start induction motor ? if yes where will we connect ?
