Lineman's Reference - XFMR LAB 앱 분석 (10월 4일)

Learn it. Wire it. Energize it. Check your work. Built by a working journeyman lineman for linemen and their apprentices. The XFMR Lab simulates distribution transformer banks driven by your own wiring — the metering, fusing, and faulting all behave the way you'd expect in the field. NEW IN 2.0 — BUILT-IN TRANSFORMER TRAINING (Replacing XFMR INFO) Six guided lessons take you from "what's a transformer?" to wiring a 3-pot bank: • Start Here — What is a Transformer? • Dual H Bushings — The Two Wirings & the Nameplate • The Tap Changer — One Pot, Multiple System Voltages • Three-Phase — The Three Phases and How They're Related • Bank Identification — Delta or Wye, Open or Closed • Your First Bank: Delta-Wye Closed (120/208) • More lessons on the way! Work the lessons in order, or jump straight to the labs. ALSO NEW IN 2.0 • The Sandbox (Beta) — wire anything from scratch in a COMPLETELY-customizable lab, with live, vector-based voltage and fault logic baked in. • Death Traps — scenario-based transformer traps linemen run into — and how to navigate them safely. • A brand-new look across every lab — new graphics, sharper, faster, & easier to read in the field. • Voltmeter you can now drag with two fingers; readings update as the leads move. • Parallel the secondary coils by hand in wye secondary labs • Stats that track lab completions, quiz scoring and for-fun stuff like the number of fuses you've blown. • User Customizations - the user can now alter the spec of their labs; from grounding to parallel coil cutover-direction, requiring the 4th cutout, tap changer implementation and more. • 2.0 is FREE for everyone who already owns XFMR Lab — thank you for years of feedback and encouragement. WHAT YOU GET Single Phase — Single Bushing · Dual Bushing Three Phase (closed) — Delta-Delta · Delta-Wye · Wye-Delta · Wye-Wye Three Phase (open) — Open Delta-Delta · Open Wye-Delta Misc — Paralleling · 4th Cutout · Death Traps (6 Scenarios) Advanced — Straight 480 · 240/480 · 277/480 · Corner-Grounded 240/480 · Wye-Wye 5-Wire (120/240 + 120/208) - all now able to be wired up Wye AND Delta on the topside The Sandbox (Beta) EVERY FUTURE UPDATE IS FREE - THE APP IS A ONE-TIME PURCHASE. I'm always working on new updates. TOOLS & REFERENCE • Volt, ohm and rotation meters with real behavior • Nameplate, secondary coil and tap changer animations • Reference diagrams for every standard bank Learning Mode walks apprentices through every wrong-connection check. Journeymen and experienced users can keep this turned off if they'd like. QUIZZES • Classic Quiz — Select each lab you want in your quiz - with graded scoring across each lab. • Advanced Quiz — You're provided with the job-site info and need to pick the right nameplate and coil setup, then wire it. • Bank ID - A beginner's quiz tied into the new XFMR Training lesson plan. The user is provided with different primary and secondary wirings and must correctly identify them. Used by 30,000+ linemen since 2021. Questions? Suggestions? Reach me at info@digitalapprentice.net
