Th Voltag Dro calculatio optio i comprise o fiv 
different types of calculations.

{1 Servic Cabl Voltag Drop- calculate th voltag dro o 
secondar conductor unde norma loadin conditions Th 
conductors must be in the conductor data file.
   
{2TransformeVoltag Drop-  calculate  th voltag dro i 
th transforme cor unde norma loadin conditions Thi 
valu shoul b adde t th servic cabl voltag dro t ge 
th tota dro see b th associate load Th transformer 
must be in the data file.


Th tw section abov hav th sam basi scree inpu design 
 sub-men wil allo yo t choos whethe yo wis t perfor 
on calculatio fo  particula situatio o whethe yo wis 
t creat  se o voltag dro table fo variou parameters 
Th tabl creatio featur i  ver valuabl featur tha 
allow yo se u  complet se o table fo eac transforme 
and conductor with different ranges of footage and load.

Th singl calculatio optio wil promp yo fo  conducto 
o transforme cod b displayin  windo o th dat fil an 
allowin yo t scrol throug th fil searchin fo you 
conducto o transformer Yo wil b prompte fo powe facto 
an loa values Th conducto calculatio wil als requir 
th entr o th numbe o phases voltage an conducto 
lengt i feet I wil als as yo t specif singl o 
parallel conductors.

Th cabl optio wil calculat th line-to-neutra an line-t 
lin voltag dro i volt an percent Th transforme optio 
wil calculat th voltag dro i percen fo th give loa 
an fo ful load Th ful loa valu ca b use a  wors 
cas堠 valu i ther ar othe load connecte t th 
transformer.

Th堠 respectiv tabl calculatio optio wil nee䠠 som 
additiona values Th cabl optio wil require  startin 
loa valu wit a increment Fo example i yo wis t star 
you tabl a 1 K an incremen i b  KW yo woul specif 
th startin loa a 1 K an loa incremen a  KW Value 
fo startin lengt an lengt o incremen i fee ar als 
needed Th transforme optio onl require th startin loa 
and load increment values.


{3CablVoltagDro fo Moto Starting-   calculate th 
voltag dro associate wit moto startin only

{4 Transforme Voltag Dro fo Moto Starting- calculate th 
voltag dro associate wit moto startin only Thi valu 
ma b adde t th Cabl Moto Startin valu t ge th tota 
drop due to starting motors.


Th tw section abov hav th sam basi scree inpu design

times the normal current can also be used.


{5 Stree Ligh Voltag Drop-  specialize sectio designe 
to calculate voltage drops for street light design.

Thi optio present yo wit  graphi representatio o  
stree ligh circuit showin cabl impedanc an luminair 
locations  tabl allowin inpu o footage conducto cod

2 an 3 the yo specif  luminaire a poin  t 1 A 
poin  t  yo specif  luminaire an  luminair a poin 
 t 3.

Afte th entr o eac lin segment th progra wil
