|CMT 2280 - Mine Electrical Maint III|
This course will fulfill the MSHA training requirements for an electrical card and can replace CMT 2250 and 2260. The course introduces the student to the theory of direct current and its use in mining equipment series, parallel, and series/parallel circuits. The theory of atomic structure, sources of electrical force, and atomic particle characteristics are also covered. Basic technology, units of measurement, symbols, and motors are discussed in detail. The student focuses on alternating current, maintaining AC mining equipment, and terminology used in electronics. An in-depth study of voltage generation, inductance, capacitance, series and parallel circuits, transformers and AC motors allows students to analyze circuit problems.
