Sir ac spd jal jati h aur inverter b jalgaya. isse pahle kuch nahi laga sakte kya. Ye 2 times hogaya. Sir pls kuch suggestions dijiye. Light fluctuation karti hai.
2 chezein krein..SPD ki earthing seperately krein takey surge inverter mein na jaye. Or SPD sy pehle voltage protection device lagadein or ek MCB , agar earthing properly hui hai to earth leakage wala MCB lagadein. Wo 0.3 amp ke difference pr trip hojata. Matlab agar phase mein 10amp jarahey hein to neutral mein 10 return aney chahye. Otherwise wo breaker trip hojaeyga. Because wo current phir kaheen aur jaraha
Sir my home elcb (robot)trip when rain start. After off ac and dc mcb near solar inverter everything fine. What causes and what i am to do. Pls suggest 🙏
Does it provide the path to earth by providing a lesser path with least resistance because the wires never pass through SPD like a normal MCB, its alwayed looped with the load. Another thing how should an AC SPD for inverter and DC SPD be wired. Most installer connect both with singular earth. They connect everything together. In that case i think it would not make any sense for SPD.
PLEASE REPLY - is it possible that even if proper AC SPD’s are installed THEN too the inverters fail because of high voltage discharge ( high voltage discharge from discom grid to ground right before the transformer input) ? Many other electronic equipment’s got burnt but no harm to inductive motors, AC SPD’s blasted on one of the site.

Agar 3 phase hai or app 4 pole SPD mein neutral nahi lagaty to phir matlab neutral ke through wohi surge leak hokr apka product kharab karsakhta. Apko neutral bhi use krni hogi. Kabhi kabhi neutral m bhi voltage ajati hai. Us cheez m bhi bachaeygi. Agar 4 pole SPD apko single phase me use krni hai to hojaeyga.

What is difference between SPD n under voltage device? Recently my lights burst n fans burnt due to over voltage n phase failure on my nearest transformer. I have bus bar installed with ACearthing but still my lights burnt . Now please guide me what should i install for my system protection SPD or under voltage device in my main DP Box .
bhai agar radiation up and down yani jaise cloudy hota hai to PR ghatne ya badhne kyo lagta hai. Kabhi ghata hone par badh jata hai aur dhoop nikalne par ghat jata hai aur fir kabhi kabhi iska ulta ho jata hai yani ghata hone par ghatne lagta hai
Bhai PR k formula mai radiation ki value division mai hoti hai , iska matlab radiation increase hoga toh PR decrease hoga , Lekin agar genration increase hogi sath mai toh PR constant bana rahe ga , agar aap k PR ki value affect ho rahe hai toh aap k plant under perform kar raha hai
how inverter will behave incase of there is no SPD ? it doesn't have any builtin protection towards high voltage ? and one more question: if we install Volt - Ampere Protector of 40 Ampere , will it give protection in case of there is no SPD ?
Thanks for explaining: I have one earthing connected with lightning arrester. Can i give same earthing to dc and ac SPD’s ? My panels are placed at 4th floor roof the height approximately 40feet from ground. I have 12 panels of 5kw. Plz suggest 2nd earthing compulsory or i can use same earthing for spd’s and inverter.
In some cases we found that installer uses varistor instead of spd, Kindly also explain which one is good , how we can find what value of varistor is suitable for site and right way to install it..
kindly clear a confusion. Some installers prefer to connect the spd to the mcb output and some prefer to the mcb input. Kindly confirm which one is better.
you have missed 1 crucial info regarding spd and how it protects. if you install it this way you will burn the spd alongwith wherever its installed. you need the maximum kA of mcb to be less than spd kA otherwise mcb won't break the circuit and your spd will burn within a few minutes.
@@nepto5817 you can use 110 v DC spd. Since your system having conductor there will be more chance to hit by surges. So to protect your system you can use SPD with Uc- 10% to 20% higher than Voc value. i.e. ~=110 v DC.
Sir, in one of my site ac spd os getting blown at B phase only i have replaced it twice but still issue isn't resolved . Kindly explain the issue and provide the solution
