Answer / the pm

voltage transformer is generally used to step down the
voltage but potential transformer is used for both step
down the voltage as well as for protection basis.

Answer / nilesh kasar mumbai

VOLTAGE TRANFORMER STEPS UP/DOWN VTG BUT PT ONLY SENSES VTG

Answer / maharaja.a

THE VOLTAGE TRANSFORMER USED ONLY BELOW 110 KV PROTECTION
BUT THE POTENTIAL TRANSFORMER USED FOR HIGHER VOLTAGES.

Answer / vishal shirke

potential transformer is used to measure voltage difference
between any two points.voltage transformer is used to
measure line voltage.

Answer / sareer ahmad lone

Basically,both these transformers perform the same
function.That is for metering and protection.

Answer / nilesh shinde

as per construction both are same but potential transformer
is always step down type transformer where as power
