A continuation of ELM103. Students will gain further knowledge in the subject areas of supplying quality power, conductors and cable, transformers, street lighting systems, revenue metering and line rigging. The line rigging segment will cover some basic principles of physics, use of formulas in line construction and how to safely lift and move field equipment using ropes, knots, splices, blocks, and slings. The laboratory segment of this course will consist of experiments based on Ohms law including resistance, voltage and current in circuits with emphasis on the use of a digital multi-meter to measure resistance, voltage and current. Other experiments will include analysis of circuits with capacitors, diodes, and transistors.
