inductive reactance is proportional to frequency and inductance. So for same inductance if frequency increases L can be decreased. where L is prop to volume. So higher the frequency lower the size required.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
