Corona Discharge - how to prevent
?
Running into corona problems
with a small loaded antenna , terminating as
a wire at the far end
Q has any one addressed this
problem and found a suitable solution ?
Apparently more prevalent on 136
khz , this is presenting on 500k , I can find
reference to rounded objects and rings , one being
two sets of ring's the second being insulated
to reduce the v/mm stress , but these where part of
a high voltage insulator with the far end
earthed , not so in this case, the wire ends in
free space ..
Increasing the surface area
will distribute the charge , but will not
reduce the stress as this is a generated field as
opposed to a static build up ?
Links / ides ?
Tnx - Graham .
