Voltage Drop Kya Hai aur Kyun Zaruri Hai?

Jab current kisi lambi cable se guzarta hai, toh cable ke internal resistance ki wajah se voltage kam ho jata hai. Is "Loss" ko **Voltage Drop** kehte hain. IEEE standards ke mutabiq, voltage drop **3% se 5%** se zyada nahi hona chahiye.

Voltage Drop ko Ignore Karne ke Nuksan:

• ❌ Motor Overheating: Low voltage ki wajah se motor zyada current (Amps) kheechti hai aur jal jati hai.
• ❌ Torque Loss: Motor ko pura dhakka (Torque) nahi milta, jisse wo load nahi utha pati.
• ❌ Equipment Malfunction: Sensitive electronic devices aur PLC low voltage par band (trip) ho jate hain.
• ❌ Electricity Waste: Voltage drop heat ke roop mein energy waste karta hai, jisse bill badhta hai.

💡 Master Engineer Tip:

Agar cable ki lambai 50 meter se zyada hai, toh hamesha ek size badi cable select karein (Next standard size) taaki voltage loss kam se kam ho.

Frequently Asked Questions

Q: Kya aluminum cable mein drop zyada hota hai?
Ans: Haan, Aluminum ka resistance Copper se zyada hota hai, isliye wahan drop zyada dekhne ko milta hai.

Q: Maximum permissible voltage drop kitna hai?
Ans: Lighting circuit ke liye 3% aur Power/Motor circuit ke liye max 5% drop allow hai.
