Repeatable exposure
Every learner can receive the same fault family without waiting for a physical rig to be rewired.
For maintenance teams · colleges · instructors
Electrical troubleshooting training with evidence—not attendance.
Give every learner repeatable hidden-fault practice in a browser. The circuit responds to each fault, the multimeter records test choices, the server scores the diagnosis, and team administrators can review and export the result.
Current scope: industrial motor-control diagnosis across DOL, reversing and star-delta circuits. It is training evidence, not a safety credential or practical competency authorisation.
Why simulation fits this skill
Fault finding is a sequence of decisions.
A slide can describe a contactor. A scored simulation can reveal whether a learner distinguishes command voltage from power-path voltage, chooses an appropriate meter mode, finds the first unexpected circuit state and commits to the diagnosis.
Scored decisions
Wrong diagnoses and unsafe meter choices remain visible in the record.
Instructor review
Member passes, averages, best scores and last activity sit beside existing team progress.
Portable evidence
Admins can export learner progress as CSV for internal review or LMS-adjacent workflows.
Visual field guide
Eight diagrams for the buyer, instructor and learner workflow.
The visuals cover pilot design, data flow, assessment scope, record fields, meter behaviour, buyer contexts, implementation and the coaching loop.
Pilot design
Validate with a small cohort first
A focused pilot tests instructional value, completion behaviour and reporting before a wider seat commitment.
Evidence flow
From simulated job to instructor report
The learner interaction and the reporting layer share one source of truth instead of relying on a self-reported completion checkbox.
Scope
Be explicit about what the browser proves
Circuit reasoning, diagnosis and meter-mode choices are visible. Practical PPE, instrument handling and real-equipment authorization are not.
Record anatomy
Review more than pass or fail
Attempts and safety mistakes show where coaching is needed even when two learners both reach the correct answer.
Safety behaviour
Make meter-mode selection part of the score
The model blocks live continuity and records the choice, reinforcing the distinction between energised voltage diagnosis and isolated resistance tests.
Use cases
One engine, distinct training contexts
Teams use the same simulation core while their assignment, review and purchasing paths remain separate from individual learning.
Implementation
A practical instructor-pilot checklist
Define the target behaviour, select cases, review evidence, compare with a practical exercise and document the simulation boundary.
Learning loop
Use evidence to choose the next case
A saved record becomes the input to coaching and targeted repetition, not the end of the learning process.
What ships now
A module inside the existing team product.
Learners use the same login and motor-control engine already in PLC Simulator Pro. The dedicated assessment route removes the visible fault controls, records the attempt and feeds the existing team reporting layer.
8 hidden work orders
DOL supply, stop, coil, contact, overload and phase cases plus reversing and star-delta interlocks.
Virtual meter evidence
Named control and power nodes, voltage, isolated continuity and an explicit live-mode safety block.
Server-owned scoring
Correct fault, diagnosis count and unsafe test choices determine a transparent 70–100 score.
Team reporting
Per-member passes, average, best, last activity and a CSV export alongside existing progress.
Pilot before rollout
Start with one instructor and 5–15 learners.
Choose two no-start cases and one dangerous-state case. Review completion, diagnosis attempts and unsafe setups, then compare the browser record with an instructor-led practical exercise. That produces the evidence for a real rollout decision.
Training record, not compliance certificate
The record shows what happened inside a simulation. It does not certify a learner for energized work, lockout/tagout, PPE selection or any standard-specific requirement. Those remain the responsibility of the employer or institution.
