Answer / neeraj julaha

I read only about corona effect when the
EHV transmissions lines which are used
on power stations
get a max value of voltage then we could
saw the corona effect its a layor of
environment gases which gets ionised
due to voltage pressure and make a
hinsing noise also as we hear when we
get under a power transmission line so
that effect is called the corona effect for a
better assistance u may call me on

ESP means Electro Static Precipetator it is work on corona effect.ESp two type of insulator used support insulator & shaft insulator. It is used Power plant, Songe Iron plant, Sinter Plant etc.

Answer / shivaleela

I am going to explain about Corona.
Mainly Ozone gas is produced by corona discharge method.
In this method , Electrodes are the main components. In one side , Oxygen is passing, another side High Voltage(5kV), is passing, Due to apply of high voltage oxygen molecules broken and formed into 0 & O. This O will get mix with O2, and form into O3 that is called Ozone gas. This Ozone is mainly used for purification of water, air treatment, STP etc. If u want more information call me 7760572952

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
