M.O.F is one of important electrical instruments which transforms high

voltage & big current of the distribution line into low voltage & small current suit-able for KWH-METER only for metering purpose.

for example) 20000V/100V, 100-50/5A means- transforms 20000V into 100V and transforms 100A(or 50A) into 5A20000V/380V(or 100V), 100-50/5A means

- transforms 20000V into 380V(or 100V) and transforms 100A(or 50A) into 5A
