Answer Posted / tanmoy
OLTC is an Onload Tapchanger. It is connected through the tapping leads to the regulating winding of the transformer.Most of the transformers have OLTC connected to the Primary winding of the transformer. However, there are tapchangers which supports bi-directional power flow, hence can operate in both primary/secondary windings of the same transformer depending on the direction of power flow. For an instance,if a step-down transformer being used as step-up transformer then based on the direction of power flow, the OLTC connected previously to the primary winding of the transformer (step-up case) will be now connected to secondary winding(step down).
Hence, it will be viable that we use the phrase regulating winding of the transformer instead of using primary & secondary winding of the transformer.
Nevertheless, the voltage regulation is achieved by utilizing desired number of turns of transformer windings segregated in taps, which can be selected as per need of required voltage.
Tapping arrangement is further bifurcated into different schemes..viz., Linear, Reversing & Coarse-Fine.
Hope, you will find the above explanation in order. Request for feedback folks.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
