    I'm doing my final year project related to load monitoring on distribution transformers. I was thinking of using Current Transformer to get the current readings at the primary side (11kV line), but one of my seniors advised me that I could use a hall effect current sensor instead, as it would make it much easier for me to use with a micro controller. I've done a bit of research on this but I'm not sure if its possible to use a hall effect current sensor at 11kv ?
    Can you please guide me if this is the right approach or should I look for another solution ?

    The Hall sensor wouldn't connect to 11kV; it would, like a current transformer, be responding to the magnetic field generated by current in an 11kV cable.

    why, when you can get a current transformer cheaper, and less complex? there are standard "relay" modules that use current transformers to determine the phase, power factor, and current. it is an industry standard.
