1.SYSTEM OVERVIEW
The Complete Training System for Transformers is an advanced, modular, and fully integrated training platform designed for comprehensive instruction in transformer technology and electrical power engineering. The system supports theoretical understanding and practical experimentation across a wide range of transformer types, electrical loads, and measurement techniques.
It includes a complete suite of hardware modules, loads, measuring instruments, power supplies, structured learning content, and an online digital education platform with full teacher–student environments.

2. TRAINING TOPICS COVERED
The system enables hands-on learning in the following areas:

• Electrical safety procedures and protective measures
• Configuration of power generation systems based on circuit diagrams
• Use of commercial measurement instruments (multimeter, oscilloscope, measuring interfaces)
• Voltage equation and equivalent circuit analysis
• No-load, load, and short-circuit testing of transformers
• Determination of inductance, magnetic coupling, and leakage reactance
• Investigation of losses, voltage regulation, and efficiency

A complete experimental guide with detailed procedures is included in both printed and digital interactive formats. PDF-only documentation is not permitted; the digital software must support teacher and student modes with and without answers.
