Hello Friends Welcome to my Channel. Here your can watch and learn pratical things about Electrical Field. I also provide project oriented knowledge and also installation, testing and maintenance of electrical Equipments/ Devices/ Accessories. So keep watching my videos and share your love. Thank you 🙏
1st check how many apfc panels are there like, is there any local apfc panel connected near to load? If yes the set the target power factor in local apfc is less than main apfc panel.
2nd if there are no apfc panels in load end then check target power factor in this apfc controller. If the power factor is not set to 0.999 then set it.
3rd case if your load is very low, in that case the apfc controller also shows ovcom ( not continuously but rapidly). To solve this problem you have to either increase the load or install 1 kvar, 2 kvar and 5 kvar capacitor bank.
And sorry that was part 6 video not part 7 in which you can completely understand about different alarms in the apfc controller. And also there are no. videos on etasmart apfc control if you watch then you will definitely get a brief idea
Iska Part 2 jaldi banaiye. Aapne HT ka voltage kitna gap hai ek tap me bataya. Par LT me ek tap change kiya to kitna difference aayega ye detail me bataiye. Jaise agar LT me single phase 260V aa raha hai to kitne tap lower karna padega, ye is tarah samajh aa jaye bas ye bhi share kijiye.
Sir mere pas bhi ye controller lga hua h but sir vo auto me nhi ho rha auto select krne pr bhi again manual me hi dekha rha hai and perimeter bhi change nhi ho rhe h how to solve this problem
1.Check your wiring of ct is proper or not. 2. Check your under current protection setting in the APFC relay. 3. If your load is very low then it may affects. 4. If there is no lower range capacitor bank ( 3/5/10 ) in APFC relay. It may creat problem.
