Most engineers confuse these two concepts!
PROTECTIVE EARTHING (PE) vs FUNCTIONAL EARTHING (FE).

During my years in control panel design, I still see this common mistake in drawings!

🎯 The difference between them:

✅ Protective Earthing (PE):
• Green/Yellow wire 🟡🟢
• Carries fault current ⚡
• Triggers breakers to protect the system
• Main purpose: Save lives! ♥️

✅ Functional Earthing (FE):
• Usually a braided strap 🔗
• Removes high-frequency noise 📢
• Improves EMC stability (Electromagnetic Compatibility)
• Main purpose: Protect electronics! 📱💻

📌 Quick takeaway:
PE = Safety First!
FE = Performance Matters!

Power Factor Capacitors improve efficiency in electrical systems by supplying reactive power to counteract inductive loads (motors, transformers).

Benefits: lower electricity costs, better system performance, avoid utility penalties, and increase network capacity.

Types:
1- fixed (for steady loads)
2- automatic (for variable loads).
