Electrical substations are energy distribution posts found throughout cities. A substation receives high-voltage electrical energy and transforms it into low-voltage streams, and distributes it to nearby homes and businesses via power lines. A 
Substation Wireman works to maintain these substations.
A substation wireman
performs routine maintenance and emergency repairs on circuit breakers, transformers, power cables, and other elements at a substation. They construct, test and maintain substation relay and control systems and identify malfunctions using wiring diagrams and testing devices such as ohmmeters, voltmeters and ammeters.
The work of a substation wireman can be very dangerous because work is often performed on energized equipment. As a result, safety is imperative. Additionally, this program requires integrity, problem solving skills, good judgement and critical thinking.
