THEORY

Introduction

This is the most ideal equipment for the class demonstration to explain the formation, due to high voltage sparking. 

This is self contained phenomena of corona and compact unit. 





Equipment

This equipment is known as HORN GAP equipment because two high voltage electrodes are of the shape of horns. 

There is specially designed high voltage transformer with center tap grounded. 

The horns are connected to the high voltage outputs of the transformer. 

For the safety of the operator the horns, which are at high Voltages, are covered with transparent cover. 

A suitable push button is provided in the front panel of the equipment. The equipment starts operating as soon as we press the button. 

The input supply is 230V .

Watch The Live Practical Experiment  :



OPERATION:- 

Provide 230V, AC to the equipment with the help of power chord provided with the equipment. 

Now press the push button in the front panel to see the Corona formation. 

The equipment continues to operate as long as we press the push button. 

We see that the spark starts from bottom of the horn , where the gap is minimum but sufficient to cause break down due to the application of 20kV. 

Now the gap goes on increasing and hence the spark also moves up and the length of the spark also increases as the gap increases and the spark vanishes at the end of the horns. 

This spark is nothing but corona formation.



OBSERVATION : Arc Generation


As we apply the high voltage to the horn gap. The spark over or breakdown will occur at the point of minimum gap of the horns. The upper layer of the air will get ionized and its density and resistance will decease So, the spark will move up progressively as the phenomenon goes on repeating until the corona reaches the peak of the horns.
