transformer is 1.5 MVA

thats fine but what about resonance frequency (parallel and series) how to calculate ? and how many steps for capacitor bank with 222KVAR ?

dear Canoeboy am sorry the reading for pf going up and down  i mean some times pf reading is 0.778 when 384937.5 W 494737.5 VA this is the worest case i will calculate for worst case power factor or what ?

95 % But What About Harmonics

697612.5 W 823125 VA 436837.5 VAR 0.848 PF

which one i have for KW three values average,minimum and maximum also for KVA three values Average,minimum and maximum

minimum 0.78 maximum 0.86 changeable according to the load

MPR-46S

yes for 9days

yes

the company give me the device reading and said you make the study  this files contain :- 1- V max , V min and V average 2- A max , A min and A average 3- THDV between Each Phase and THDI for each line current 4- KW , KVAR , KVA and PF for each reading 15 min reading time so, more values

dear canoeboy this files for 9 days reading that the device saved

thanks for every one now i have 5 or 6 file that have all value can any one help me to analyze them
