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.
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
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
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

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.
I feel more confident about testing motor relays and look forward to putting these lessons into practice.
What would you tell someone who was thinking about a purchase?*
this is excellent training; this is how we should be testing relays
What frustrated you most about your day-to-day testing work?
I felt confident about testing relays, but I like the philosophy taught in the class. We would find more settings problems if we simulated faults without masking elements.
Do you have a specific example or big win you could share?
Learning to use the dynamic test plans was a big help and could be applied to reclosers and other relays.
How do you feel about relay testing now?
I feel more confident about testing motor relays and look forward to putting these lessons into practice.
Outside of Buying one of Chris's books. The best return on your investment
How did you feel about testing relays before your purchase?
I was not comfortable testing relays outside of simple E-M before the course.
How did the material help you?
I have a greater understanding of the principles and the tool to accomplish what I want to test in the relays

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.
Definitely get started with this course
If you're new to digital relays and want to feel confident when approaching them in the field, definitely get started with this course.
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.
Definitely worth the effort
Definitely worth the effort, you will learn not only techniques of relay testing, but exemplary professionalism as well. The courses prepare one to be a good relay tester instead of “Button Pusher” or a mediocre one. Better yet, you might’ve found yourself a field support.
Get hold of “The Relay Testing Handbook” by Chris Werstiuk, very good review on related power system theories and excellent guide line for the training course.
Worth Every Penny
I highly recommend this course...don't hesitate. It is worth every penny. Chris is an outstanding instructor with real world experience and he will keep the class interested the entire time.
This is the most compressive relay training program I have ever seen.
I have already recommended the program to employees at my previous job. This is the most compressive relay training program I have ever seen.
Given by a tester, for testers
I was really impressed with the instructor's knowledge of both the test equipment and the relays which we tested. I have been to several advanced relay training courses and this was by far the best yet. It is great that it is given by a tester, for testers. I highly recommend this course to anyone who tests relays no matter what their skill set is.
Good way to get CEU's and a refresher in relay testing (even for an engineer).
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.
Get your thinking cap on
Get your thinking cap on, this class is for students serious about advancing there relay testing career but it is not easy.
This is an excellent course
This is an excellent course, the instructor Chris was very knowledgeable and helpful in answering all of our questions.
The material was very inclusive of all the things I would expect to encounter during relay testing. It simplified the procedures, and boosted my confidence going forward.
Chris was knowledgeable and professional throughout the entire process. We had real world problems come up in our hands on labs that aided in figuring out the issues that can arise during testing.
Even seasoned (you can’t teach me anything) relay techs are captivated by the instructor’s enthusiasm and experience.
Live training courses are NOT presented in a one-size-fits-all, take-it-or-leave-it format. The instructor’s experience allows him to tailor the content on-the-fly to fit each student’s background and experience.
Even seasoned (you can’t teach me anything) relay techs are captivated by the instructor’s enthusiasm and experience.
Engineers attending the courses leave with an understanding of the importance and challenges of specifying effective and complete field testing.
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!
Great instruction. Great class.
This is a great class; even if you have little to no experience with relays. Chris can really break things down to the most basic level. Great instruction. Great class.
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.
Great hands-on training
Great hands-on training with a detailed visual guide. Chris’ experience in the field allows him to bring real world application to the classroom. The hands-on training keeps you engaged and helps you understand the theory of operation. I can’t wait to participate in the advanced course in the upcoming weeks.
I think the cost of this training was the best money I ever spent for continuing education training.
What would you tell someone who was thinking about a purchase?
I think the cost of this training was the best money I ever spent for continuing education training. The information passed on was exactly the knowledge I needed to refresh and expand. This training captured my full attention. I thoroughly enjoyed it.
How did you feel about testing relays before your purchase?
I tested relays manually (mechanical and microprocessor) for a number of years before I got any automated equipment so I feel like I have a solid understanding of what is being simulated during testing. Once we got into using automated testing software I could not stand how button-pushers were being sent out to "test relays" and never prove any logic or even determine if the relay will actually trip. But in our industry market time is money so get out there and test as many relays as humanly possible as quickly as possible. I typically take the time needed to prove the important components so I am confident the relay will perform as intended.
How did the material help you?
I am very interested in the dynamic test methods and will be implementing them soon to our test methods. I also saw some test setup methods that apply specifically to my test set that will also help me out in the future.
How do you feel about relay testing now?
I have been reinvigorated! I'm ready to regroup and teach our junior techs some better quality relay testing.
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.
This course is a vital look into not just relay testing...
This course is a vital look into not just relay testing, but how the relay operates in a system. The information offered in this course will cut time spent researching relays and developing test plans.
its well worth the time and money spent
How did you feel about testing relays before your purchase?
comfortable but stressed
How did the material help you?

Chris Does a Great Job
Chris does a great job ! It is very obvious he has a lot of knowledge, backed up by experience. His patience, and dynamic personality, made for a comfortable learning environment.
I would definitely recommend his classes.
One of the best investments in your future career as a protective relay technician you'll make.
Boost your knowledge and confidence to analyze protection schemes and creating thorough relay test plans & reports.
The course shared options of testing multiple outputs when tripping the 86 lockouts by placing the outputs in series. Instead of checking just one of the lockout outputs assigned to that element.
I would highly recommend due to straight forward and relevant content
How did you feel about testing relays before your purchase?
I was working with relays and was always concentrated on control and signal processing equipment applicational challenges
How did the material help you?
Helped me combine some of my various practical background knowledge into more organized and straight forward technical application
How do you feel about relay testing now?
Better - more prepared and technically confident
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.
Learn it the right way, and why it's right, and you'll be golden!
What would you tell someone who was thinking about taking the course?
My thinking is that if you were to complete and retain the knowledge in this course, one could cut years of "trial and error" experience from your career.
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.
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!

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.
