As per this scheme, the Supply (Load) Current sensing CT
is put between the source and the PF correction capacitor
banks. This is as per diagram shown above. The voltage
feedback is taken from the L.T. bus system itself.
This type of scheme is used when user is interested in
maintaining the healthy Power factor on secondary side of
the transformer.
