About this app

THIS EDITION REQUIRES AN ACCESS CODE.

XFMR Lab Enterprise is the classroom edition of XFMR Lab, licensed to utilities, cooperatives and lineman training programs. Your school or employer gives you a code, you enter it once, and the app opens. There is nothing to buy inside the app, and it does nothing without a code. Buying for yourself? Search Google Play for Lineman's Reference - XFMR Lab and purchase that edition.

Wire it. Energize it. Find out what went wrong before you do it in the bucket. XFMR Lab simulates utility distribution transformer banks with the meters, fuses and fault behavior you would see on the pole. Built by a working journeyman lineman for apprentices and crews who would rather make their mistakes here than in the field.

FOR INSTRUCTORS

The Instructor Board runs a class from a tablet or a phone. Start a session, give students the join code, and assign labs to the whole class, a group or one student. As they work you see each student's wiring live on your screen, along with failed checks, blown fuses, hazards and their score. Students can raise a hand, skip a lab for a second look, or say I don't know. You can mark a lab assisted when you walked them through it. Homework sessions stay open for days with a due time. At the end the results are on your board and export as a CSV.

FOR STUDENTS

Join a session with a code and a nickname. Your instructor sees your progress while a lab is open, and the card on your screen says exactly what they can and cannot see. Outside a session, every lab and reference below is yours to practice on.

PRIVACY

No accounts, no ads, no tracking. A class session sends your nickname, your results and, in a live class, your wiring to your instructor's board. Your nickname is erased from our servers when the class ends. The full policy is at linemanapps.com/enterprise/privacy
