Review: "Electrotecnia" by Pablo Alcalde San Miguel Electrotecnia

by Pablo Alcalde San Miguel is a cornerstone textbook for students and professionals in the electrical and electronics industry. Published by Ediciones Paraninfo

, it is specifically designed to meet the requirements of the Vocational Training (Ciclo Formativo) for Electrical and Automatic Installations. Core Content and Structure

The book is praised for its pedagogical approach, balancing scientific rigor with practical application. It typically covers 21 didactic units, including: Fundamentals

: Basic electricity concepts, resistance, power, and energy. Electrotecnia Pablo Alcalde San Miguel Pdf

: Series, parallel, and mixed circuits, as well as complex multi-mesh resolution. Electromagnetism

: Study of magnetic circuits, transformers, and electric motors. Advanced Topics

: Three-phase systems, electronics (diodes and transistors), and measuring instruments. Real-world Application

: Includes guidance on electrification projects for residential housing, often updated to reflect current regulations like the RBT (Low Voltage Electrotechnical Regulations). Why It’s a Standard Resource Calculate load current: I = P_total / (V·pf)

: The author uses clear language and visual aids to explain complex phenomena like the thermal and chemical effects of electricity. Practicality

: Each unit contains numerous practical cases and solved exercises, making it a reliable tool for self-study and classroom use. Professional Relevance

: Beyond students, it serves as a refresher for active technicians looking to reinforce their knowledge of electrical laws and analysis techniques. Accessing the Material While snippets and previews are available on platforms like Google Books Casa del Libro

3. Resistive power calculations & wiring sizing

• Calculate load current: I = P_total / (V·pf) for single-phase; for three-phase I = P_total / (√3·V·pf).
• Select conductor size by current, temperature, permissible voltage drop (≤3–5% typical), and derating factors.
• Voltage drop: ΔV = I·R·L (single run) or use per-table values for copper/AL.
• Protective device rating: choose breaker/fuse ≥ expected load current but ≤ conductor ampacity + safety margins.

Is the book available in English?

Yes, a translated version exists, but the original Spanish is the most comprehensive. If you are an English speaker, you might look for Electrical Engineering by Hambley as a companion, but for the specific Alcalde style, you should learn the Spanish technical terms.

7. Rotating machines — brief practical guide

• DC motors: torque ∝ armature current; control via armature voltage or field weakening.
• Induction motors:
  • Squirrel-cage: common for industry; slip s = (Ns − N)/Ns.
  • Starting methods: direct-on-line (DOL), star-delta, soft-starter, VFD for torque/speed control.
• Synchronous machines: used for generators and power-factor correction (operate at synchronous speed).
• Selection: match torque, speed, duty cycle; consider starting current and protection.

5. Single-phase vs three-phase

• Single-phase: Vline = Vphase.
• Balanced three-phase:
  • Line-to-line voltage V_L = √3·V_phase.
  • Line current for delta/wye loads per configuration.
• Power (three-phase): P = √3·V_L·I_L·cosφ (active).

7. Electrical Machines

A thorough study of transformers, asynchronous motors, synchronous motors, and alternators. The book includes wiring diagrams and troubleshooting tips.

Can I pass the Spanish "Electrical Installations" exam with just this PDF?

Yes. Most technical schools and Trade exam boards (like the Examen de Grado Medio o Superior) base their curriculum almost entirely on Alcalde San Miguel’s work. However, you should also check local amendments to the REBT.
