ABSTRACT:
An insulated point gap assembly for a toroidal coupled telemetry system wherein a drill collar (38), operable to be connected to a lower portion of a drill string (32), carries a toroidal core having primary windings (88) and secondary windings (130). An aperture (154) is laterally fashioned through the drill collar. A conductor (150) is connected to one end of the secondary and extends through the aperture and the other end of the secondary is connected to the drill collar. The conductor is surrounded by an electrical insulation member (152). In a preferred embodiment, an axially extending sleeve of insulating material (156) is applied about the drill collar at the location of the conductor (150) to further isolate the conductor 15 from the drill collar.
