This course covers electrical schematics, controls and switches used by the industrial maintenance industry. Students are introduced to the ammeter, voltmeter, ohmmeter, wattmeter, multi meter and direct digital meter. I Study of the effects of phase angles, frequency, vectors, current, impedance, capacitance and power. Students develop diagnostic knowledge and skills through calculations and analysis of electrical circuits. Through classroom theory and hands-on application, students use electrical schematics and direct digital meters to diagnose electrical failures.
Course covers theory, diagrams, pressure and ratio calculations, and work and power principles.
Through classroom theory and hands-on practice, students develop basic knowledge and skills in solid state controls and circuits. Distribution systems are covered, including network types, grounding systems and protection of systems. Introduction to ASA standard marking system and differences between three phase and single phase transformers. Some prior knowledge of AC is recommended. Students develop knowledge and skills in theory and construction of induction and squirrel cage motors.
