सर जी अगर SPD के अर्थिंग को घर के अर्थिंग के साथ कनेक्ट करेंगे तो 11000 वोल्ट घर के अर्थिंग में चला जायेगा जे की फिर से वापस घर में आ जायेगा। इससे बचने के लिए क्या हमे दो अर्थिंग करना पड़ेगा एक SPD के लिए और एक घर के लिए।
Sir I have 2 meter one single phase and one 3 phase on my ground and first floor. Earthing 1 hi extra hai. Kya ek earthing me dono meter ke spd ,single phase ki or 3 phase ki join kar sakte hain kya
Well done Bro. Have no doubt on the connection now. One question, As our regular power supply voltage is 230-240, This model will only Earth out voltage above 385 V ?? will it be safe for electronic devices ?
SPD should be installed first afterwards the two pole MCB then RCCB and single pole MCB's because as per the above installation the MCB will drip down or get burnt first in case of surge and hence SPD will not do its task.
SPD is connected in parallel, so that the surge can also flow to the remaining circuit? Or the SPD bypasses it into the earth? What is actually happening here.
Yes. It bypass it to the earth. only lightning current (which is 20KA-40KA) flows through main current wire whether it is a neutral or phase it will earthing. the surge can only pass through meter, DP-mcb, and SPD. Next circuit remains safe. If more then 40KA current passes through main Line then fuse will blown or transformer may blast at the main line transformer. So home wiring will be safe..
Bohat achey se ap nay guide kiya aur SPD ky connection kernay ka tareeka bataya.... aik question hai..... jo earth power supply Company deyte hai hum kiya Company nay jo apna earth deya hai es earth ko SPD se connect ker saktey hain
sir this is khuram here from pakistan. kindly tell me if we do not having earthing in my home how i use spd in my home....secondly if we connect earthing point to any floor area is it working.........?
Good explanation, tell me one thing plz, my earthing is only 24 feet deep. So if i connect that earthing with spd then i can get same benefits or i have to make my earthing more deeper ?
Abe 24 feet😰 mera ghar mei 5 feet earthing hei. And wo achcha kaam kar raha hei. Mera ghar ko 10 saal hua. Ab tak koi problem nahi aaya. Even ghar near forest area mei hei aur udhar bijli ki current main line mei pakadta hei. Hardly i lost chip board of TV, Washing machine and chimney. And I only installed 4 DP-MCB for 2 G&F floor Inverter current and another 2 for AEH current. Main meter->fuge->4DP-Mcb i didn't even installed DP MCB, RCCB,SPD for whole house.
Total fake knowledge de rahe ho, kisne kaha h ki jiske ghar me earthing nhi h wo SPD use nhi kar sakta aur 3000-4000Rs tak nhi milta maine to 800Rs me kharida kuch din pahle.
usmai Over Voltage and Under voltage par minimum 5 sec wait karega tripping ke liye aesa device buy karo jisko hum aapne requirment ke according Delay Time Set kar sake
SPD connect after two pole MCB is to protect your SPD from instant burning, SPD cost a lot more than MCB. By doing this you get protection for the Home and also for your SPD device
