Corona is a pale blue discharge caused by an intense electric field breaking down the insulating properties of air. It normally occurs at sharp corners or points on energised high-voltage conductors, where the electric field is particularly intense. It can also occur at the surface of single, narrow, conductors -which is why very high-voltage transmission line conductors are bundled in groups of two (e.g. 275-kV lines in the UK) or more (e.g. four in the case of 400-kV lines in the UK).
So a corona is caused by voltage (electric fields) , whether a load current (magnetic fields) is flowing or not. So a load is not neccessary for corona discharge to occur.
What else can I help you with?
What actually happens when load is applied to the beam and why does this condition occur?
the beam gets bend if the load is more then the resisting force of the beam and if the resisting force is more then the load it doesn't bends.
What is the effect of an inductive or capacitive load under no load conditions?
A load of any type,,,inductive or capacitive , would effect the circuit even if THOSE "loads" had no load on them. They would still have a load effect on the circuit they are connected to.Answer'Under no-load conditions' means that no load is connected to the supply. So your question doesn't make sense!
How line current is measured at no load condition?
The same as it is when loaded. Under no load condition, the line current is due to the capacitive effect of the line to ground. No load current, therefore, can be calculated based on the characteristics of the line. I've never seen someone attempt to measure this current, for example to help size sectionalizing switches. I've only ever used the calculated values.
What is mean by no load condition?
Commonly relates to devices or equipment which are designed to do some task involving delivery of power, electrical or mechanical. The receiver or this power is called the "load" (for example, a light bulb, or a public lift activated by a motor). If such a load is disconnected (electrically or mechanically) then the arrangement is said to be in a "No Load" condition, and in some cases this might result in some electrical or mechanical failure of the power provider, possibly permanent. Good equipment is designed so that such failures do not occur.
Effect of changing load on alternator?
by changing load its terminal voltage changes.

The command for taking the weapon from Condition 4 to Condition 1 is Lock and Load?
false
What is loading effect?
An instrument to be able to really tell the value is mandatory that the instrument does not load the circuit making it a false reading or inaccurate loading effect which means when we give high load that may be cause to some fake or inaccurate of output, this may be known as loading effect....
What does no load condition refer to?
If transformer then it refers to that, the primary is charged, but secondary is open, (no load is connected) If motor, it refers to that no load is connected to motor, the shaft is decoupled from the load, but running with out any load.
Is loading effect more when load impedance is less then source impedance?
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
Small effort to lift the load of 1st class lever?
This will occur if the fulcrum is closer to the load than the effort
