Electrical Resistivity of Concrete— A Literature Review This report constitutes a literature review of the electrical resistivity of concrete. Electricalresistivity is an important consideration in such applications as grade crossings and concreterailway ties, where stray currents may disrupt... BDA ...
at 3.3.KV, 16.7Hz. The high-voltage distribution system at 50 Hz supply is converted to this electric motor rating by transformers and frequency converters. This system employs two overhead lines, and the track rail forms another phase, but this raises many problems at crossings and junctions....
