WIND-ELECTRIC GENERATING PLANT FOR CATHODIC PROTECTION OF PIPELINES Russian patent published in 1998 - IPC

Abstract RU 2117184 C1

FIELD: corrosion protection of oil, gas, and water intake wells. SUBSTANCE: current- conversion system includes polarization-voltage pulse amplitude shaping unit; pulse length is found from equation , where τ_p is pulse length; τ_pot is time required to shape permissible potential U_max; U(t) is current value of polarization voltage. EFFECT: enlarged service life of anodic grounding electrodes. 1 dwg
