Real material
Wiring devices, boxes, consumer units and connectors drawn from the manufacturers' datasheets: terminals, dimensions and screws as on the real product.
Electrical simulator for vocational training · REBT
An electrical trainer built on real physics
Installation tasks, fault diagnosis by measuring and checks against the REBT — no material used and no live voltage.

Your AI · MCP
Voltaula works with your AI
Connect your AI assistant — Claude or any other MCP-compatible one — and ask for scenarios in your own words. The AI creates a draft in your scenario builder; you review it and you publish it.
Only in the edition for schools, and only for teachers.
You choose the permissions
- Catalog, faults and REBT rulesRead only · required
- Create and edit my draftsOn by default
- Assign tasks to my groupsOff by default
The AI cannot see students
Nor their attempts, scores or chat: the connection has no such functions.
You publish
The AI creates drafts. Assigning tasks only if you allow it: published scenarios only, your groups only.
What you practise
Everything that happens on a job, in a simulator
Voltaula is an interactive simulation platform for electrical installations, built for training and practice: equipment behaviour is physically computed, faults are diagnosed by measuring, and teachers get training tools.
Realism
Built with workshop precision
Every part is drawn from its datasheet, and every action costs what it costs on a real job.
0 V
Safety first
Isolate, lock off with a padlock and prove dead between L–N, L–PE and N–PE before touching anything.
Measurements, not guesswork
The instruments respond like real ones, because they measure the computed circuit.
Tools of the trade
Each tool does what it does on site, and every action takes its time.
ITC
REBT rules
Every installation is checked against the REBT rules and their ITCs; every error carries its reference.

Five languages
Spanish, Valencian, English, Russian and Ukrainian, with translation of technical terms if you need it.
€
Every mistake costs
Material used and working time are counted as in a real quote.
No risk
Here a short circuit only trips the breaker.
No material wasted
Practise as many times as you need, or with limited material if the teacher decides so.
Explain your decision
If you depart from the rules for a reason, you write it down and the teacher decides.
Languages
The interface in one language, the terms in another too
Two independent settings: the interface language — any of the five — and, if you want, a translation of technical terms into any of the other four. Everyone works in the language they understand best and learns the electrical terminology in two languages: the one on screen and the one needed in the workshop, on site or in the documentation.
- Interface languageSpanish, Valencian, English, Russian or Ukrainian: tasks, menus and report in the language you choose.
- Term translationOptional: next to each technical term, in brackets, its name in any of the other four languages.
Who it is for
- Students from abroad: the interface in their language, the terms in Spanish as they are said in the workshop and on site
- Schools teaching in Valencian: the interface in Valencian and the terms in Spanish, or the other way round
- Students preparing to work abroad or with manufacturers' documentation: the terms in English too
- Teachers: in one group, each student with their own pair of languages

For teachers
Your class, live
A dashboard for the teacher: groups, assignments with deadlines, live sessions and a step-by-step review of every attempt.
- Groups with an access code and email invitations
- Assignments with a deadline and number of attempts
- Live session: see the screens, take control, freeze or write in the chat; exam mode
- Scenario builder: floor plan, points, routes and your own faults
- Step-by-step replay, comment and your own score; accept the student's explanation or not
- The group's most common mistakes and CSV export

Write to usNo. Voltaula runs in the browser: all you need is a computer and an internet connection.
No. It is for preparing and revising: students arrive at the workshop with installation, measurements and fault finding already practised.
The Spanish Low Voltage Electrotechnical Regulation (REBT, 2002) and its complementary technical instructions (ITC-BT). Every rule carries its reference: the clause of the regulation or good installation practice.
Yes. Teachers connect their AI assistant (Claude or any other MCP-compatible one) and ask for scenarios in their own words; the AI creates a draft and the teacher publishes it. The AI cannot see students, their attempts, scores or chat.
How it worksWith their email (they receive an access link), with Google if the school has enabled it, or with the group code their teacher gives them.
Spanish, Valencian, English, Russian and Ukrainian. Technical terms can also be shown with their translation into another language.
It is used only for training. The school decides how long attempts are kept, and a student's data can be exported or deleted on request.
Write to us at info@voltaula.study and we will set up access for the school, its teachers and its groups.
