Hi, a good day to you at EPP.
I am an entrepreneur looking into setting up a cassava starch manufacturing factory. The power requirement of the processing line is about 180 – 200kwh.
Firstly, I will like to ask – is your organization based in Nigeria?
Secondly, I want to ask that for this kind of project, how much will it cost If your team or organization were to install this project? Let us assume the plant site is 15km away from a 33KVA power source.
Have not visited the site for a long time. The Excel calculation Spreadsheets can not be downloaded anymore.
Hello,i am Ismaila from Nigeria,i have installed a 1mva transformer and a 500kv one,i keep having an over voltage reading of above 250v when read on face to neutral and over 450v face to face reading.i am sure that my neutral grounding is adequate and efficient.i have also factored my incoming voltage and arrived at most appropriate TAP,i have also altered all TAPS and all produces till yet high voltages.pls advice on any other options i may have..Thank u 4 your anticipated support.
What is the % of load you are ruining the Tr-r. at?
