Garmi ka mausam shuru hote hi ek samasya har ghar mein dikhne lagti hai — bijli ka dim hona. Kabhi fan itni dheere chalta hai ki hawa nahi lagti, toh kabhi AC baar-baar "Khat-Khat" ki awaz karke band ho jata hai. Bahut se log turant bijli vibhag ko koshne lagte hain, lekin ek electrical technician hone ke naate maine dekha hai ki har baar galti transformer ki nahi hoti.
Kayi baar samasya aapke meter se lekar ghar ke board ke beech chhipi hoti hai. Aaj hum detail mein baat karenge ki low voltage kyun aati hai aur ise ghar par kaise theek karein.
⚠️ Yaad rakhein: Low voltage ek chhoti samasya nahi hai. Agar ise ignore kiya toh mehenge appliances kharab ho sakte hain aur bijli ka bill bhi badh sakta hai.
Low Voltage Aane Ke 5 Asli Karan
1. Neutral Wire Mein Carbon Ya Looseness
Main apne 10 saal ke experience se keh sakta hoon ki low voltage ka 60% kaaran "Neutral" mein dikkat hona hai. Agar aapke main switch ya meter ke paas Neutral ka taar dhila hai, toh voltage drop hone lagti hai. Kayi baar joints par barish ya nami ki wajah se carbon jam jata hai, jo bijli ke raste mein rukawat banta hai. Isse voltage kabhi 150V toh kabhi 180V hi reh jati hai.
Pichle mahine mai ek ghar par gaya jahan poore ghar ki light dim thi. Jab maine main board check kiya, to wahan neutral wire itna loose tha ki wo sparking karke kaala pad gaya tha. Sirf us connection ko tight karne se voltage turant 220V ho gayi.

2. Area Overloading Aur Transformer Par Load
Garmiyon mein jab poori gali ek saath AC aur water pump chalti hai, toh local transformer apni capacity se zyada load lene lagta hai. Is situation mein transformer "baith" jata hai aur voltage automatic gir jati hai. Agar aapke padosi ke ghar mein bhi wahi samasya hai, toh samajh lijiye ki ye problem transformer side se hai, ghar ki wiring se nahi.
3. Service Wire Ka Patla Hona
Kayi log ghar ke andar toh achhi wiring karwate hain, lekin khambe (pole) se meter tak aane wala taar (Service Cable) sasta aur patla lagwa lete hain. Jab ghar ka heavy load jaise AC ya Fridge chalta hai, toh patla taar garam hone lagta hai aur "Resistance" ki wajah se voltage drop kar deta hai. Hamesha dhyaan rakhein ki 2 Ton AC wale ghar mein kam se kam 6mm ya 10mm ki service cable honi chahiye.

4. Phase Imbalance Ki Samasya
Hamari galiyon mein 3-Phase ki supply hoti hai. Agar pados ke sabhi gharon ne ek hi phase par load daal diya hai, toh wo phase kamzor pad jayega, jabki baaki do phase par voltage sahi rahegi. Isliye agar aapke padosi ki light tez hai aur aapki dim, toh iska matlab hai ki aapka "Phase" overloaded hai. Aise mein electricity board ke lineman se apna phase badalwana ek aasaan solution hota hai.
5. Main Switch Aur MCB Mein Kharaabi
Hamare ghar ka main switch ya MCB box purana hone par uske contacts kamzor ho jate hain. Yahan se hone wali sparking ya loose connection voltage ko poore ghar tak nahi pahunchne deti. Ek baar apne MCB box ko zaroor check karwaein ki kahin koi taar jala hua ya pighla hua toh nahi hai.

Ghar Ki Wiring Ki Samasya Hai Ya Transformer Ki — Kaise Pehchanen?
| Situation | Problem Kahan Hai |
|---|---|
| Sirf aapke ghar mein voltage low hai | Ghar ki wiring ya neutral |
| Pure mohalle mein ek saath dim hai | Transformer overload |
| Raat ko theek, din mein dim | Transformer par daytime load |
| Ek kamre mein dim, doosre mein theek | Us circuit ki wiring ya MCB |
Low Voltage Ko Sahi Kaise Karein?
Connections tight karein: Sabse pehle apne meter aur MCB box ke saare joints check karke tight karein. Ye ek kaam aksar simple screwdriver se ho jata hai lekin bahut fark padta hai.
Phase change karwayein: Agar problem sirf aapke phase mein hai, toh electricity board ke lineman se bolkar apna phase badalwa sakte hain.
Proper earthing karwayein: Ek achhi earthing low voltage ki samasya ko kaafi had tak sambhaal sakti hai. Ghar ki earthing sahi hai ya nahi ye jaanchne ke liye — Ghar Ki Earthing Kaise Check Karein
Voltage stabilizer lagwayein: Agar transformer ki taraf se hi voltage low hai, toh ek achha mainline copper stabilizer lagwana hi permanent solution hai. Ye 150V ko bhi 220V mein badal deta hai. Stabilizer ke baare mein poori jankari — Stabilizer Kya Hai? Kya Har Ghar Mein Lagana Zaruri Hai?

FAQ (Aksar Pooche Jaane Wale Sawaal)
Q: Kya low voltage mein fridge chalana safe hai?
Bilkul nahi. Low voltage mein compressor par zyada load padta hai aur wo jal sakta hai. Agar voltage lagatar 180V se neeche aa rahi hai toh fridge ke liye stabilizer zaroor lagwayein.
Q: Kaise pata karein ki galti transformer ki hai ya ghar ki?
Agar padosi ke ghar ki light bhi dim hai toh transformer ki galti hai. Agar sirf aapke ghar mein dikkat hai toh wiring check karwaein.
Q: Kya purani wiring se voltage drop hoti hai?
Haan, purani wiring mein joints zyada hote hain aur taar andar se kamzor ho jate hain, jo voltage drop ka karan bante hain. 15-20 saal purani wiring hai toh ek baar electrician se check zaroor karwayein.
Q: Low voltage mein AC chalana chahiye ya nahi?
Agar voltage 200V se neeche ja rahi hai toh AC band rakhein ya stabilizer ke saath chalayein. Voltage fluctuation se AC ka compressor kharab ho sakta hai jo bahut mehenga padta hai.

Conclusion
Low voltage ek aisi samasya hai jo dheere dheere aapke ghar ke saare bade appliances ko nuksaan pahuncha sakti hai. Ise "thodi si bijli ki problem" samajhkar ignore karna samajhdari nahi hai. Sabse pehle ye pata kare ki problem ghar ke andar hai ya transformer side se — phir uske hisaab se solution lagaye. Agar neutral ya wiring ki dikkat hai toh ek baar kisi qualified electrician se check zaroor karwaye.
