In the transmission lines, there is no apparent change in the condition of air(CORONA) surounding the wires if the applied voltage is low.However,when the applied voltage exceeds the certain value,called disruptive voltage !!!

What is armature voltage?
critical.
What is the function of monitoring voltage relay?
A voltage monitor relay is in the circuit for one reason. It monitors the incoming voltage to the equipment that it is protecting usually on three phase control panels.The relay monitors the three incoming line voltages and in some relays the voltage to ground (wye connection). If the circuit the relay is protecting looses one of the voltage legs, the circuit will shut down until the problem is rectified. This usually happens if a fuse blows in one of the three phase voltage legs.It also monitors the level of voltage to the circuit. If the voltage drops due to a malfunction in the utility lines the relay will trip and take the protected circuit off line. The voltages can be set to trip at any under or over voltage usually by set point controls on the front of the voltage monitoring relay.
What type of selection that acts against individuals of an intermediate type?
disruptive
Is a voltage source a zero or infinite impedance?
Obviously it's not infinite impedance--that would mean it soaks up all the voltage. It can't be zero impedance either...that would be a superconductor, and there aren't many of those around. Voltage sources have impedance, but it's not infinite. Sometimes the impedance of the source is critical--radio frequency amplifiers have to be impedance matched to their transmitting antennas if you don't want to burn them out.
What are probable causes for not have build up voltage in a shunt generator?
1. Field Flashing. 2. Resistance of the filed winding should be less than critical field resistance. 3. Speed of the motor should be greater than critical speed. 4. Interchange the field connections. 5. Check the commutator surface and brush.
What is critical impulse flash over voltage?
This is the peak voltage for a 50% probability of flashover or disruptive charge.
What are the possible remedies against corona because of extra high voltage?
increase the size of conductor ,provide the hallow conductor,increase the critical disruptive voltage bv providing shunt capacitors. these capacitors increases the power capacity of the line.
What is armature voltage?
critical.
What is the comparative and superlative form of the word disruptive?
more disruptive, most disruptive
What is a sentence of disruptive?
Bad teacher has a disruptive influence on children.
How do you spell disruptive?
That is the correct spelling of "disruptive" (causing upset or disturbance).
Selection occurs when the environment continually eliminates extremes at both ends of a range of phenotypes?
Stabilizing selection.
When was Disruptive Technology Office created?
Disruptive Technology Office was created in 1998.
What kind of gene mutation is most disruptive to an organism?
Deletion is most disruptive to an organism.
