The Electrical Library contains 10 courses regarding the various tools, documents and equipment used by the petroleum industry from ammeters to AC/DC motors. Electricity is vital to the operations on a rig, platform or any other oil and gas facility. AC/DC motor theory and maintenance courses teach electricians, mechanics and technicians the necessary skills to operate and maintain motors used by oil and gas companies. Wiring a facility requires a complete knowledge of conduit systems, including installation, bending, conduit types and components. Once installed, the maintenance and proper use of these systems depends on the ability of site electricians and electronics technicians to read electrical prints, use a wide range of tools and meters, and troubleshoot problems. As always, safety training for personnel working with and around powerful electric systems increases awareness and helps prevent accidents.
