Why there is no corona in DC transmission?
Bcoz, corona effect is only possible in high voltage AC supply due to the frequency. That is, the frequency and the HT voltage causes the arc b/w 2 conductors.so , here the air is act as the arc transmitting medium.we called it as Corona. It is highly impossible in DC bcoz of no frequency.
What frequency corona loss is more?
frequency is directly propotional to corona loss... so higher the freq the corona also high..
What is the Frequency Supply in UAE?
Supply Frequency in UAE is 50Hz
Where can someone purchase a Smith Corona ribbon?
One can purchase a Smith Corona ribbon on websites like Smith Corona Type Writer, Amazon, Office Depot, Typer Writers Supply, Smith Corona or BB Crafts.
Does the value of the exciting current of your 3-phase motor depend on the rotor speed?
An induction motor has no excitation, so the question is about a synchronous motor. The rotor speed is determined by the supply frequency. For a given supply frequency and mechanical load, the excitation current can be adjusted to give the best power factor.
What does Hotbird network search frequency depend on?
The Hotbird network search frequency will depend on where you live and how far you are from a tower.
What is the standard frequency and on which factors does it depend on?
standard frequency in India is 50Hz
What does a pitch of sound depend on?
Frequency
Does the pitch of sound depend on the frequency of the sound waves that produce it?
yes, the pitch of sound does, in fact, depend on the frequency of the sound wave.
If a bulb has 50 Hz frequency and it is apply at 60 Hz frequency voltage supply then it is glow or not?
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
What happen to the frequency if the electrical line has a load?
Frequency is set by the supply, not by the load.
What happens to the resistance when the frequency is doubled?
Impedance of a coil or a capacitor does depend on the excitation frequency,but resistance has no relationship to frequency.
