For voltages above 100KV, the conventional type of PT becomes extremely expensive due to insulation
A stack of high voltage capacitors forms the potential divider, capacitance of two sections being C1 and C2 respectively, Z is burden.
The Intermediate transformer's primary voltage is usually above 10 Kv.
Value of L is adjusted to 1/ w2( C1+C2) so that vol drop due to current from divider is compensated. So transformation ratio is independent of burden.
