11KV LINES A.C.S.R CONDUCTOR VOLTAGE REGULATION.

11KV LINES A.C.S.R CONDUCTOR VOLTAGE REGULATION TABLE.













Its maintain a fixed voltage under different  varying load. Generally voltage regulation is a limiting factor which decide dimensions of conductor and insulator used in it.

voltage  Regulation for 11kv,22kv & 33kv over-headed line.

voltage regulation are calculated as-
               
                    % voltage regulations = (1.6 * power*L*PF)/ (LDF * RC *DF)
                     
 - power  in KVA
-  L- total length in KM from sending to receiving end
- PF- power factor in PER UNIT ( p.u )   
-RC- Regulation Constant (KVA-KM) per1%  drop

LDF- Load Distribution Factor

DF- Diversity Factor in PER UNIT.


KW-KM FOR 11KV  3-PHASE LINE FOR 1% VOLTAGE DROP.

* for a conductor temperature 60 and 50 degree Celsius   above figure would be 3% higher and for temperature 70 degree Celsius  about 3% lower
