System earthing is how your system neutral is connected to earth. if neutral is not provided then derived neutral is used.
solidly earthed, neutral grounding resistor , inductor, neutral grounding transformer are some ways of system earthing

What will happen if power transformer designed for 50 Hz is connected to 500 Hz of the same voltage , and vice versa ?

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
