CONE 2225

Transformers

Credits: 2

Description: This course covers the concepts of transformer operation. Single-phase and three-phase (polyphase) transformer operation and installation methods are explored. Included in the course are the following topics: transformer operation, transformation relationships, transformer losses, transformer types, transformer testing, series and parallel operation, connections, instrument transformers, and maintenance procedures. National Electrical Code requirements for transformer installations are developed and utilized. Prerequisite(s): CONE1108

Credit Breakdown: 0/2/0 (Lecture/Lab/On the job training)
