With this online course, you understand what is going on and how to interpret results. I really like this course.
I would definitely get this online training. Its broken down to the basics and takes you through a step by step process. You cant go wrong with this. It is worth every penny. It even has websites you can research if you're unfamiliar with the material.
Most of the test sets does the work for you with a push of a button. With this online course you understand what is going on and how to interpret results. I really like this course.
The videos and presentations on this course have been very helpful and given me a better edge on what is going on in the relay testing industry.
Worth every time spent on the training
Worth every time spent on the training, very practical and educational, it gave me both practical view of relay testing and educational understanding of relay testing
- How did you feel about testing relays before your purchase?
Most of the time I felt like I was a good copier of relay testing - How did the material help you?
Educating in aspects of power system and its protection - How do you feel about relay testing now?
Confident and with an understanding of protection
It would be difficult to overstate the value of his classes.
I've done enough coursework in my life in various disciplines and trade crafts to have forgotten some of them. In all of my studies, I have rarely met an instructor who knew their material better, delivered it more clearly and effectively, or who obviously enjoyed teaching their subject more. His class helped me understand relay testing at a level far above what I knew before I took it. It would be difficult to overstate the value of his classes.
I wish I had found your books a while ago.
I have just bought your protection relay testing set of books about a few weeks ago and I just wanted to say that I’m very impressed with it.
I have been commissioning power systems for a few years and I wish I had found your books a while ago.
its well worth the time and money spent

Very well priced, Chris goes into extreme detail and cares about setting you up for success in your testing future.
This course should be mandatory to anyone entering into relay testing!
This course should be mandatory to anyone entering into relay testing! I feel that they should have a little experience under their belt with the basics of talking to the relay, changing settings, using a test set to test elements, etc, but certainly a must in my book!
I enjoyed the step by step instructions and the amount of informative material
There is a ton of great information and it really helps to see the step by step process that is actually explaining what were doing when we test relays and not just moving on once there's the green checkmark.
I had a wonderful experience
Do it. I had a wonderful experience and learned an immense amount about troubleshooting relays and the test sets.

This is a great source of knowledge that may have been over looked or not even taught. A resource I will definitely be going back to when I'm prepping for a job or have a question that the videos answer.
I have been so impressed with the booklet
I have been in electrical testing for the past 15 years and have worked for NETA shops and utilities. The booklet is excellent for a beginner as well as a seasoned test technician. I purchased this for a look at another’s perspective on end-to-end relay testing. Included are test plans, connections, procedures and testing philosophies. The user will find an overview of nearly all of the popular protection strategies as well as a very helpful overview chart.
I have been so impressed with the booklet that I will purchase the expansive relay manual.
Bravo Mr. Werstiuk, (author), you have accomplished in a few pages the equivalent of a semester of test school.
This course...is super handy in the field.
This course will help you sort out which brands use which system to depict phase angles. That is super handy in the field.
This Course is a Must...
This course is a must for relay testing engineers who struggle with the testing of more advanced relay functions such as line distance and transformer differential. Instruction on the background and theory of the functions is followed by hands-on testing of these functions on relays that are commonly encountered in the field.
Well worth the money and best training I've had.

The best investment of time and money you could make as a Relay Tech
What would you advise students who are interested in this course?
Review any of Chris's YouTube videos that relate to the relays you will be going over, and if possible purchase the Relay seminar video and review the modules that pertain to "Dynamic testing", it will be the best investment of time and money you could make as a Relay Tech.
It's Amazing!
Do not hesitate not even for a second if you want to learn the right way to test and commission a protection relay just go ahead and take this course
Made me more aware of how easy it is to operate and test Digital Relays
How did you feel about testing relays before the course?
I am a bit apprehensive with the New Test Equipment for Digital Relays

How do you feel about relay testing now?
Not got an issue now
Why should someone take this course?
Massive benefits. The Tutor is so advanced in his techniques. Also he has shown the correct way in testing.
...try to understand what the relay is intended to do and how you can test it as a whole.
Don't focus solely on Enoserv testing, instead try to understand what the relay is intended to do and how you can test it as a whole.
I would recommend these courses to anyone
I picked your courses because they looked interesting and they were inexpensive.
I was not disappointed, I found them very informative and quite easy to follow.
I would recommend these courses to anyone needing continuing education or just wanting to learn more about relays.
I learned a lot and look forward to taking more classes from Valence.
Very good training
Very good training to help someone understand what to look for in phase relationship with what you will see in the real world of relays.
I look forward to future classes!
If you test relays, this class is a must. I lacked experience with generator relays and the combination of hands-on testing and theoretical knowledge about the elements in test created a seamless transition from the classroom to the field. Outstanding professor with many ways to explain the same thing. I look forward to future classes!
Keep up the good work
I work for a testing company and I always wanted to get better with relays but found it difficult to learn more on-site since we don’t usually have much time to play around. Our company owns Omicron and Doble test-sets and was able to borrow them over the week ends. I would grab an SEL relay and follow you step by step and learned a lot that way.
I practiced a lot doing manual pick up and timing test (without changing settings) to get a good foundation and now slowly getting into dynamic testing.
I also purchased your Relay Testing Handbook and find it very useful on-site. I keep the soft copy on my laptop so I can refer to it very easily.
I recommend this course to anyone who wants to get better at testing relays.
Looking forward to more videos from Valence.
Keep up the good work
This is a great beginner course to 3-phase power for relay testers
This is a great beginner course to 3-phase power for relay testers that are thrown in to relay testing through programs rather than having the electrical theory to back up troubleshooting and expected results.
There is a wealth of information and a lot to be learned
Take it, there is a wealth of information and a lot to be learned about electromechanical relay testing and digital relay testing
You wont regret it
This course helped me understand what true relay testing is, Dynamic testing is truly fun to learn & not so boring as you would just button pushing.
You wont regret it.
I highly recommend this course!
I found this course to be very useful in understanding the fundamentals of three-phase power systems. It was extremely easy to follow along. Very clear, cadenced rhythm with the video narration allowed me to understand without having to backtrack.
The course material would be suitable for technicians or students looking to get a grasp on three-phase power systems and converting between cycles and seconds; a must have for any relay technician.
I appreciated the real world examples and exercises, which will help me when I come across these specific problems in the microprocessor based world of protection relays.
Overall I highly recommend this course!
Wonderful course
Wonderful course that really digs into generation protection while keeping it interesting and informative. The hands-on approach really aids in the retaining of knowledge!
For an inexperienced tester like myself, he made it easy to follow and understand
Chris was an excellent instructor. For an inexperienced tester like myself, he made it easy to follow and understand. I was never bored once in the 3 days. I had never used the Doble or its software before, and now I’m confident I have a great base to continue my learning.
Chris has a natural talent for teaching!
Chris has an incredible amount of knowledge and experience which he shares as he teaches the theory and practical methods of relay testing. These experiences are so valuable whether you are new or an experienced veteran of relay testing. You get theory and then the opportunity to set up different testing situations to apply and prove the lessons. You can experiment with the circuits and test until you are proficient. Regardless of the brand of test-set, Chris is there to assist and offer advice until you are comfortable with the testing circuit and the test-set's available functions. Excellent opportunity to learn the strengths and weaknesses of different brands of relay test-sets. Chris has a natural talent for teaching!
Chris is an excellent instructor that was able to teach at everyone’s level from beginner to advance
Chris is an excellent instructor that was able to teach at everyone’s level from beginner to advance. Chris didn’t move on until he felt everyone had a grasp of what he was teaching, so nobody got left behind. I like the fact that Chris taught from his experience and not from a book written by some else. I look forward to taking other classes with Chris.
This is the best training I have seen for 3 phase power systems!
This is the best training I have seen for 3 phase power systems! The animations are terrific. These are things that I am constantly drawing by hand to help illustrate concepts to other technicians but they just aren't the same when I can't draw them in motion. The links to other sites that are referenced have an abundance of additional theory topics and more animated illustrations. I very highly recommend this course.
This Course is Fantastic
This course is fantastic for all who look to gain a better understanding of how relays work, as well as how to test those relays.
Great idea and I actually learned quite a bit.
I think this is a great avenue for training.
I think this will help me a lot in future applications. I saved the provided excel sheet for future use.
Good way to get CEU's and a refresher in relay testing (even for an engineer).
I would recommend anyone who uses SEL to take your classes.
I am really new to the SEL relays but was invited to sit in on the end to end testing class.
Even though I am not familiar with the Accelerator software and don't have any experience so far, I really enjoyed your passion for teaching what you know!
I hope to take some of your other classes in the future.
Great course with excellent pedagogy.
The screen shot for each lesson was well organized. Having the spreadsheet, test set software, video camera on the relay, relay software, notes, and red outlining for selected feature made it very easy for me to follow your narration. Then you broke each topic into less than 15 minute chunks allowing me to absorb the topic and digest the new information before starting the next lesson. Very well done.
It is worth taking
It is worth taking because it is designed to help you regardless of your knowledge level and you can learn at your own pace.
I found the Phasor Diagrams for Relay Testers course to be outstanding.
It filled several gaps in my understanding of phasor diagrams. I found a number of valuable insights.
I am happy to highly recommend the course for any P&C Tech regardless of experience.
I am looking forward to taking additional training courses.
Thank you.
very informative and digestible for anyone at any level of knowledge.
very informative and digestible for anyone at any level of knowledge.
The course was very useful and beneficial
What did you enjoy most about the course?
Learning to test the elements manually without the use of automated software and being shown how the relay actually operates and senses readings.
Understanding phase angle relationships to simulate faults.
This was a very good refresher for me.
What would you tell someone who was thinking about a purchase?
I scribble phasor diagrams everyday while explaining systems, simulations, or theory. It behooves every NETA technician level 2 and up to be able to understand the relationship between the generator, the sine wave, and the phasor diagram.
The small classroom sizes make for a good learning environment.
Valence Electrical Training Services instructors break every generator protection element down into manageable sections. The small classroom sizes make for a good learning environment.
Experienced Instructor
Chris is extremely knowledgeable and experienced. He has seen almost every mistake that can be made in the protection and control game. This course will provide you with a great step-by-step guide to testing. Not only will you have a good guide, but you will understand WHY you are doing that step.
Very Well Presented
The information in this course was very well presented. The practice sheets make the concepts more easily understood. I would recommend this course to anyone who is involved with electrical power systems.

Relay testing handbook is well written based on real relay testing scenarios,
i am really satisfied with this book which can explain the difficult things in a easy way.
thanks for the author of the book.

I recently attended the Relay Testing Fundamentals course and highly recommend the on line and hands on training courses to any level of personnel from beginner to senior level in the electrical protection and control testing and commissioning fields.
Chris’ time and dedication to the industry shows in the testing techniques he has acquired and teaches in the courses. All participants that complete the on line and hands on training courses will become more thorough and efficient at relay testing and P&C commissioning. I found the course itinerary, delivery and the equipment provided made it easy to learn and understand all concepts discussed. I also believe all participants will be more confident and better prepared to provide their employer and/or clients with a better final product delivered with confidence. I will definitely be attending all future training courses.
