摘要：There is discussed an idea for implementation of five conducting IT system (with insulated neutral) for power networks in the underground mines and open pits. Its qualities are analyzed on the background of the applied three phase (3Р+РЕ) .Т system with insulated neutral. Problems are considered regarding the electrical safety, technical possibilities for reaction and its economical efficiency. Advantages and disadvantages of the five conducting (3Р+N+PE)system are systemized and analyzed in comparison with the applied (3Р+РЕ) four conducting system on the background of the specific features and requirements during electrification of underground mines and open pits
