## What is Power System Lab?

Power System Lab helps cadets and marine electro-technical officers understand electrical principles, practise their skills and revisit difficult topics.

Understand before you answer
Explore 33 topics covering electrical fundamentals, generators, motors, protection, automation, measurements and ship systems. The library contains 575 learning steps with 412 short checks: plain-language explanations, worked examples, illustrations and interactive models.

Before a new test, study material selected for its questions. Change the topic or test length to practise what you need. You can also open full topics from the library or go straight to the test.

Try it on a virtual instrument
Use 16 practice benches to connect probes, select a measurement mode, adjust values and interpret results. Practise voltage and resistance measurements, current loops, PWM signals, timers and other tasks. Feedback helps you understand what to change and why.

Keep useful tools at hand
The Tools section brings together 18 tools, including electrical calculators, signal scaling, Pt100/Pt1000 calculations, unit conversion, resistor codes and Modbus register conversion. See formulas and explanations alongside results. Create several ship clocks, give them your own names and choose a fixed UTC offset or a city's time zone.

Build a steady learning habit
Revisit mistakes, bookmark questions and use spaced review. Track completed tests, your daily goal and progress. The leaderboard and local study reminders are optional.

Continue on the web
Use the same account at powersystemlab.net/app/. Reading progress, completed instrument practice, favourite tools and ship clock settings synchronize when online.

English and Russian
The interface, topics and exercises support both languages. The available learning path is electro-technical officer.

An account is required. After signing in, topics, virtual models, tools and ship clocks can be used without an internet connection while your account remains available on the device. New tests, sending answers and synchronizing test results require internet access. Reset a forgotten password by email or delete your account in Settings.

This version is free. This version has no ads, subscriptions or in-app purchases.

For independent study and reference. The app does not provide professional certification or replace formal training, equipment documentation, vessel procedures or safety requirements. Calculations and virtual instruments use the assumptions shown in the app.
