Abstract

This article focuses on networks with great phase voltage unbalance. Formerly, it was necessary to operate these networks with an isolated neutral, resistance or solid grounding. The three-phase compensation system eliminates phase voltage unbalance and can substitute or complement the arc-suppression coil. This system enables a more effective operation of distribution networks with non-effectively grounded node, even in networks with
a significantly high capacity unbalance.
