Purpose of PT
Purpose of PT
(OP)
In a Harmonic Filter circuit(tuned LC circuit) Switchgear, a 34.5/0.11Kv PT is connected across feeder terminal with one terminal of secondary connected to earth. No other load is connected.
Is the Pt could be conneted for discharge the charge of capacitor bank.
Would helpful by your valualbel support.

Power-class capacitors are supposed to have internal bleeder resistors. I’d guess the PT is for basic harmonic/bus-voltage measurements, assuming that everything else is symmetrical and not needing more sophisticated checks.
