Testing & Maintenance of Electrical Systems (SCTP module)
About This Course
This module provides students with knowledge and understanding of the testing and maintenance of electrical systems. Student will learn about the types, construction and configurations of switchboards, metering and protection requirements, maintenance, inspection and testing of switchboards, electricity code of practices and regulations, tests conducted before and after turn-on, lock-out tag-out procedures. This module will also cover operation, control and maintenance of standby generators and the design and testing of photovoltaic systems
