ELT3040 Generation/Transformation

Advanced · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students operate, experiment with and analyze alternators and transformers used in power generation and distribution.
Prerequisite: ELT1030: Conversion & Distribution
Parameters: Access to an AC/DC motor generator set, a transformer kit, AC/DC volt ampmeters, a multimeter and related resources. Note: The student must have access to instruction from an individual with electrical technologist or journeyperson status when students are operating low voltage alternators.
