Understanding basic electrical theory will significantly reduce the time and cost for maintenance and repair of power distribution and support equipment. This class provides an in depth discussion on the basics of electricity. Continuing from Basic Electricity I, this course concentrates on the more complex components. We provide detailed descriptions of the operation of lead-acid batteries and their associated monitoring and control systems, motor controllers, solid state UPS units, and major distribution circuit breakers. We will also include a comprehensive power distribution system analysis, including load sharing, adjusting field excitation and manual paralleling operations. Having a more thorough knowledge of these systems increases efficiency in diagnostics and operation while simultaneously providing a higher level of baseline knowledge concerning the energies present, thereby increasing the safety of the technician.
