Description

This free online course provides an in-depth and practical understanding of the principles of electricity that affect battery maintenance and electric currents. We delve into electric distribution systems, performance tests and the maintenance of electrical equipment. We also lay out the fundamental definitions and laws of electricity and magnetic induction. The course covers electron theory, electromotive force (EMF), voltage and current in electrical circuitry before moving on to alternating current, power factor calculations and the working of electrical circuits. Batteries are an essential feature of ships and their maintenance can affect safety at sea. We go through the description, operation and layout scheme of marine electrical machinery. We then lay out the operating principles of electrical generators and motors as we examine their shipboard distribution, insulation properties and common challenges. This course then investigates the inspection, safety concerns and maintenance of marine electrical machinery, which requires continual monitoring, testing and attention to stay in good working order.

We explore the concepts of resistance, resistivity and inductance and explain the difference between electrical elements and networks. We outline the color-coding of capacitors and break down the factors affecting their capacitance value. We then investigate the flow of electrons on an atomic level. The course then moves on to the components, types and mechanics of batteries and their chargers as we examine their application, performance, maintenance and troubleshooting methods. We cover electrolysis and the internal resistance and polarity of batteries before laying out the factors that increase the risk of electric shock in the marine environment along with its quick treatment. We take you through the safety management requirements of marine systems and identify the steps taken to prevent electrical shock. The course breaks down the basic laws of electricity, including Kirchhoff's laws, Ohm's law and those governing energy and power. We compare series and parallel connections and demonstrate the usage of direct current (DC) voltages in various circuits.

This course clarifies basic concepts pertaining to electrical currents and electromagnetism as well as the practical alternating current (AC) generator. We teach you the reactions of circuits consisting of resistors, inductors and capacitors. We then show you the layout of AC and DC shipboard installation in addition to the ship's navigation light circuit. The course outlines marine power distribution systems along with the concept of high- and low-voltage application. We identify the types and methodology of electrical maintenance and show you how to maintain DC machines, alternators and induction motors. We demonstrate the process of detecting electric malfunctions and describe measures to prevent further damage. We then go through the maintenance of switchboards. The course wraps up with an analysis of the function, configuration and performance tests of marine electrical equipment and its monitoring systems. This course suits electricians, marine engineers and anyone working at sea as we provide the information and skills you need to keep ships safe and moving.
