Following are the Points In which we describe the whole process.

o Causes

o Measures

o Comparisono Advantages

o We explain each step in detail.

Losses due to Voltage Drop:


7/23

We have 11kv wapda feeder having capacity of 4300kw.xisting syste!

have three transfor!ers of 4"00#$% with o&t p&t of 400$.

If we i!prove o&r voltages on o&tp&t of transfor!er we can save a lot of

cost we are paying in the for! of lectric bills ' (achine repairing.

)ere we consider the two cases at different voltage val&es.

Causes:

In other words we are paying 6s 1,700 extra to wapda in the for! of electricity

bill. It can be !ini!i8ed by i!proving o&r o&tp&t voltages to re9&ired level.

%s we have seen in the previo&s slide7 if we i!prove o&r syste! voltage to40v we can save a!o&nt of 6s1,700 on daily basis.

:his profit is on 1(w load.

We can save a lot of !oney in the for! of !achine life and its efficiency.

If we increase load profit will increase accordingly.

If we consider it on sa!e load with one !onth period ' in a ;ear.

re9&ire!ent> so that we can get the !axi!&! o&tp&t with best profit . -y its i!ple!entation we can have the desired o&tp&t which also i!proves

!achine life and efficiency which is also a pl&s point.

&teps taken '! us to eliminate voltage drop:

We have planned to install on load ).: ?tabili8er on o&r c&rrent syste!.

?ie!ens is providing on/load ).: stabili8er in Pakistan.
