Abstract:
An inground isolator and associated method can provide an electrically isolated break in a drill string using electrical insulating members/isolators that are supported by a housing. During drill string operations, the isolators are subject only compressive forces responsive to both extension (pushing) and retraction (pulling) by the drill string. The isolators can be formed from an electrically insulating material such as a ceramic material. An interchangeable inground tool system is described which integrally serves to provide an electrically isolating gap in the drill string.

Claim (Index 1):
An apparatus for use in combination with an electrically conductive drill string and which drill string extends from an inground distal end, including an inground tool, to a drill rig, said apparatus comprising:\n a plurality of electrical isolators; and a housing defining a through passage and having an elongated housing length that is configured to support the plurality of electrical isolators under a compressive preload that is applied by the housing such that an overall compressive force that is applied to the electrical isolators decreases responsive to push forces that are applied to the drill string by the drill rig and the electrical isolators cooperate with the housing to form an electrically isolating gap between the inground distal end and the drill rig.
