Substation Maintenance Technicians Certification

Substation maintenance is a key part of any plant’s maintenance program. Failures in key components such as racking mechanisms, meters, relays and busses are the most common causes of unplanned outages. Transmission, distribution and switching substations generally have switching, protection and control equipment and one or more transformers. Having skilled substation maintenance technicians is essential to equipment reliability. This certification program will qualify technicians to safely maintain the wide array of equipment in a substation.

What is certification? Certification means you have achieved certain performance criteria – knowledge, skills and abilities through training. Certifications prove your skills, and their value is the recognition of customers, coworkers and employers. This certification also meets the requirements of OSHA 29 CFR 1910.269(a)(2)(vii).
