Is anyone familiar with transformer neutral grounding systems and can point me to the right standards that guides their design and installations, on the same note if you have any formulas on this I would highly appreciate

Hi there,
It is not really my area of expertise, but you may find the Cahiers Techniques series (index and some missing volumes not on that site are also available here) provides some helpful background information.
HV and LV earthing are discussed specifically
https://studiecd.dk/cahiers_techniques/Neutral_earthing_in_an_industrial_HV_network.pdf
discusses neutral earthing via resistors, reactors and resonators, and fault currents.
https://studiecd.dk/cahiers_techniques/System_earthings_worldwide_and_evolutions.pdf
is more general and describes practice in various parts of the world.
discusses LV earthing particularly.
Probably worth a look, if there is anything new to you.
regards
Mike.
