1. Single-line-to-earth fault limitation through the setting of Petersen coil in power transformer neutral / Limitação de correntes de falta fase-terra por meio do ajuste de bobina de petersen em neutro de transformadores de potência
The Petersen coil insertion on the neutral of the electrical distribution power system transformers has been a technical strategy adopted for several electrical utilities, in many countries with the purpose to reduce the earth-fault current intensities, enabling circuit disconnect decrease for intermittent faults and so to improve the electrical power qualit
