How big (size) can the tertiary winding be in transformer?
Can we load the tertiary winding, if yes then how much we
can load it?

Answer Posted / rabramovitz

Tyically for stabilizing an oscillating neutral, about 35%
of the KVA (or VA) supplied. Yes, it can be loaded, as long
as you don't exceed the current rating for its gage (do not
exceed current which causes a temp rise at or below the
class of the transformer). The current capability (if
properly designed)will be about a third of a primary phase
current normalized to the tertiary ratio. (call it NI/3)on
a per phase basis.

What happens if the Capacitive Voltage Transformer Primary neutral is not earthed. There is a CVT between Transformer and source, and the CVT neutral of the transformer is not earthed, does it effect the transformer while charging or does it effect the transformer charging process.
