EEG: Electrical Engineer Guide
Learn how a building is fed
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
A field guide for new electrical engineers: how power reaches a building, what lives inside a distribution board, and the everyday sums -- all offline.
EEG is a training app for electrical engineers early in their career, and for students and technicians who want to understand how a building actually gets its power.
It works entirely offline. There is no account, no sign-in, and nothing is sent anywhere.
LEARN
Twelve short units, unlocked in order, take you from the power station to the socket: the grid chain and its voltages, the board hierarchy, protection devices, earthing, cables, lighting and sockets, and what a shock current does to a body. Each unit ends in questions, and three find-the-fault drills put a load schedule in front of you and ask you to spot the mistake.
DAILY PRACTICE
Ten questions a day, drawn from everything in the app. The same set all day, a new one tomorrow.
CALCULATORS
Seventeen everyday tools: current from power, phase balance, breaker sizing, cable ampacity, voltage drop, transformer sizing, earth conductor size, earth-leakage rating, motor starting current, AC and water-heater loads, generator sizing, and a unit converter. Every one shows its formula and its assumptions.
REFERENCE
A 49-term glossary in both languages, 25 drawn symbols, protection-device and cable tables, a lighting and socket guide, a labelled cutaway of a distribution board, how to read a load schedule, and a site checklist you can tick off.
POWER FLOW
The single line from generation to your premises, drawn as a diagram you can tap stage by stage to see the voltage there and what changes it.
BUILT FOR THE GULF
Values are typical Gulf / IEC practice — 415 V three-phase, 240 V single-phase, 50 Hz — kept in one profile rather than scattered through the screens.
ARABIC AND ENGLISH
Both languages are first-class, with the whole layout mirroring for Arabic. Light and dark themes throughout, including the diagrams.
