How it Works:
This online seminar contains over 30 hours of videos (usually less than 15 minutes each) that you can watch at your own pace in any order with an internet connection. You have unlimited, 24/7 access to all the videos with no expiration date. Each video has closed captioning, fast-forward/rewind/play speed controls, and you can revisit the videos whenever you wish. You can learn how to use these features by clicking the Get Help menu at the top of every page.
We try to follow a “Show, Don’t Tell” philosophy in all our videos and use realistic conditions as much as possible. You can watch the instructor test different relays with different test-sets and explain what he is doing every step of the way. We didn’t cut out the mistakes he made while testing and creating the settings, so you will also see how to troubleshoot problems when they happen.
We encourage you to ask questions in the comments below each video. If you are asking about something specific in the video, please add the timestamp in the video where your question came from so that we can get you answers more quickly.
You will get a certificate of achievement when you complete all of the topics and lessons in the seminar that you can use for continuing education credits with your organization. Please let us know if you need any help getting accreditation with your organization. We will do the best we can to help you.
This course is eligible for 32 NETA Continuing Technical Development Credits (CTDs). NETA Certified Technicians (Level III and Level IV) are required to earn a minimum of 48 CTDs every three years to maintain their certification. For more information about the CTD program and requirements, please contact the NETA office at [email protected] or 888-300-6382.
