“I have had the pleasure of knowing and working with Josh Nichols and Jason Leary for more than ten years, and there is truly only one word that describes them both: brilliant.
Together, they have built what has become a world‑recognized transformer training system through Three Phase Innovations and its sister company, URD Phasing Innovations. Their passion, craftsmanship, and relentless pursuit of excellence have made their products the gold standard for lineman training across the industry.
Three Phase Innovations, a Tennessee‑based manufacturer specializing in high‑fidelity lineman training equipment, continues to strengthen its impact on the electrical workforce through innovative simulation tools that accurately mirror real‑world field conditions. Their commitment to realism, safety, and educational value has transformed the way linemen are trained.
Innovative Training Models Designed for Safety and Realism
At the core of their success is a line of scale‑model transformer training systems engineered with remarkable precision. These models:
- Simulate on‑site electrical distribution with true‑to‑life accuracy
- Are fully portable, easily dismantlable, and constructed from durable, reliable components
- Allow instructors to recreate critical field scenarios—without the danger associated with energized equipment
Each unit is designed with safety at the forefront, incorporating features such as insulating properties and a Fault Current Reactor that ensures both personnel and equipment remain protected throughout training sessions. Every model also undergoes rigorous testing to meet the company’s standards for 208VAC–120VAC power distribution, ensuring consistency and reliability across every deployment.
A Trusted Partner in Lineman Apprenticeship Training
Organizations throughout the industry rely on their exemplary work. SELCAT proudly uses equipment from both Three Phase Innovations and URD Phasing Innovations for all of its training needs. Every SELCAT apprentice develops their foundational skills using these training systems, and the results speak for themselves—safer, more confident, and better‑prepared linemen entering the field.
I continue to be amazed by the innovations Josh and Jason bring forward year after year. Their ongoing improvements to equipment and curriculum elevate the quality of training and set a higher standard for the entire electrical industry.
Their dedication is not just impressive—it is transformative. And I am grateful to have witnessed their growth, their ingenuity, and their unwavering commitment to excellence firsthand.”

Every time we have a transformer class I’m still amazed at what it is capable of doing. What is truly amazing is watching the students become engaged through hands on training.
Logan H. Cobb, Instructor, IBEW Local 702
Have you ever had to try to put something into words and it wasn’t easy to say? Three Phase innovations transformer trainer is not one of those things. Every time we have a transformer class I’m still amazed at what it is capable of doing. What is truly amazing is watching the students become engaged through hands on training.
Three Phase Innovations transformer trainer is what has been missing in lineman’s training. It brings learning to life in a way that gets the students excited about being in the classroom. As lineman we like to put our hands on everything, the model allows the students to do just that. When you have students that are excited to learn it takes class-room production to another level.
By recognizing that our students are the future of the IBEW it only makes sense to invest in the best. As instructors we are continually looking for new ways and ideas to teach our students. Three Phase Innovations has done just that. The quality and craftsmanship that they put into their models is second to none. As an instructor, I believe that with the 3 Phase Innovations transformer trainer you are only limited by your imagination.

The Three Phase Innovations training equipment Is a must have for anyone in linework, whether a line school student, apprentice, or seasoned Journeyman lineman.

The Three Phase Innovations training equipment Is a must have for anyone in linework, whether a line school student, apprentice, or seasoned Journeyman lineman. At KCKCC we have both the overhead and underground trainers and with this equipment I am able to provide a depth of instruction in the shop than most will ever get in their career.
We also use the equipment to teach lockout tagout, switching orders, communication skills (COMIN” HOT!), phasing, trouble shooting, and electrical safety. As a Journeyman Lineman for over thirty years, I am surprised at how many different situations that can be recreated from issues that I have found in the field and can use those for a more comprehensive level of training.
Great equipment comes from a great company, and you find no better than Three Phase Innovations when it comes to service after the sale. An “extremely valuable relationship” is what you get when you deal with Three Phase Innovations.

Learn How We
CHANGED THE LINEMAN TRAINING INDUSTRY
Established in 2015, Three Phase Innovations has sold over 60 models across the US and Canada. Our main goal with our training equipment and curriculum is to provide transformer training in a controlled classroom environment. The model allows an instructor to go over the very basic scientific principles on how transformers work through electromagnetic induction to properly hook up a single-phase service to three phase banks and even learning how paralleling transformer banks together through vectoring.
Learn How We Changed the Lineman Training Industry
Established in 2015, Three Phase Innovations has sold over 60 models across the US and Canada. Our main goal with our training equipment and curriculum is to provide transformer training in a controlled classroom environment. The model allows an instructor to go over the very basic scientific principles on how transformers work through electromagnetic induction to properly hook up a single-phase service to three phase banks and even learning how paralleling transformer banks together through vectoring. The model keeps students engaged in learning, prevents them from having to deal with weather issues, and keeps focus on the training in the classroom.
Being able to work in the classroom with a range of secondary voltages from 120/240 to 277/480 allows students to work with the exact same voltage they will see in the field for the customer. Our models let instructors create all kinds of troubleshooting scenarios students will see in the field, as well as show them mistakes they will make without causing any harm to the equipment or themselves while learning. Our models provide safety features and display how to properly install a transformer on the job using continuity and polarity tests like traditional lineman used to. It covers many safety features and brings back some of the knowledge that has been forgotten over the years by experienced lineman.
Our models help students who are just discovering AC (Alternating Current) and three phase power generation and how it relates to inductive equipment such as transformers. Our models also allow for more advanced scenarios that not even some of the most experienced lineman might not see until late in their careers. Some examples would be a corner grounded delta bank, a floating wye-delta, or maybe even an open wye-open wye bank. Since the model has real transformers with real secondary voltage, anything can be accomplished just as it would be in the field. Our models cover a wide range of training that demonstrate some of the basic lineman principles, such as transformer polarity, as well as more complex skills such as troubleshooting an open or closed bank and paralleling them together properly.
