Form of workGeneral Statement of DutiesThis employee, in departments other than Traffic Engineering, performs the work as a Substation Maintenance Technician on voltages up to 138,000. This position may direct work of others in more difficult and complex types of electrical work including work on high Voltage. Work includes more advanced technical knowledge of electrical controls and complex devices.
Duties include layout and installation, maintenance, repair, replacement, adjustment, inspecting, cleaning, testing, and troubleshooting of electric and electro-mechanical systems and component parts. Employee troubleshoots on electrical, hydraulic or pneumatic controls and low voltage control wiring on any type of equipment or tools; works on buildings, grounds, machinery, sound and alarm systems, in the field, or at the shop; may be assigned to work in confined areas or at unusual heights such as scaffolding, aerial ladders, bucket trucks, poles, or other building structures or water towers; uses and analyses thermography; works with Variable Frequency Drive (VFD) units and on equipment that operates on 5000 or more voltages (high Voltage), single phase and three phase wiring which may include machinery, distribution systems, switchgear, transformers, sub-stations, control circuits, etc., and their components.
