  • Electric current pick-up shoe
    Patent number: 6323636
    Abstract: The invention concerns an electric current pick-up shoe compensating fluxes generated in a magnetic circuit (1) by respectively a primary current and a compensating current circulating in a secondary coil. Said secondary coil (5) comprises at its surface a layer of spires (12) forming a protective winding connected to a fixed electric potential (13), such that the effect of leakage capacities between the primary current conductor (4) and the secondary coil (5) winding (6) are practically eliminated.
