MV networks have numerus of solutions how to perform a neutral point grounding according to demanded characteristic of a ground fault current for relay terminals and safety of people and utilities. Solution with grounding over partial compensation is widely spread in networks with significant capacitive current I C (though not too high) and where network is mostly in a steady state without often change of its configuration. In networks where secondary side of the transformer is in delta connection grounding transformer forms an artificial neutral point through its grounding bank. Use of grounding transformer changes ground fault in a way presented in this article. Through Thevenin's symmetrical component model of a related circuit is possible to validate currents and voltages in network during a ground fault.
