Answer / thowsif_emerson_csm team

The CT Will Burn....

Why does opening a CT's secondary cause dangerously high
secondary voltage?
With the flow of both primary and secondary currents the
transformer's exciting current is very low. The secondary
current mmf serves to keep the magnetizing flux in check!
If the secondary now opens the primary current mmf produces
an exciting current 'orders of magnitude' greater than
normal. And, the resultant large increase in flux density
produces an extremely high voltage in the secondary.
