ELECTRICAL SYSTEMS FOR RAPID TRANSIT RAILROADS

Two new circuit elements have made possible new and improved electrical systems for rapid transit railroads. These are the thyristor and the parametric transformer which utilizes variation of inductance instead of flux for energy transfer. The inherent properties of the parametric transformer are of substantial advantage in electric traction since they provide overload protection, filter action, voltage regulation, and a 90-deg phase shift.
