Abstract
An electrical power system comprising a support configured for interconnection within a subsurface drillstring, an electrical power unit coupled to the support, and a conductive link configured to distribute electrical power from the electrical power unit to at least one component coupled to the electrical power system within the subsurface drillstring.
Claims21
An electrical power system, comprising:
- a support configured for interconnection within a subsurface drillstring;
- an electrical power unit coupled to the support;
- and
- a conductive link configured to distribute electrical power from the electrical power unit to at least one component coupled to the electrical power system within the subsurface drillstring.
