Dear Sir,
I need help for calculating the voltage drop in following cases:
Brief:
We plan to draw 110VAC/50Hz @ 150A UPS single phase power from Point A to Point B, which is approx 600 meters away.
2 Core cable(s) is/are proposed to be laid over the ground and will be drawn through cable trays.
One Core of cable will be connected to Phase and 2nd Core will be connected to Neutral.
The peak summer temperature range in our area is between 35-45 Deg C.
The minimum temp in winters can be between 10-15 Deg C.
We have two cable options: Copper cables 2c 300 Sq mm OR 2c 400 Sq. mm with following specs:
2c 300Sq. mm:
DC Resistance in ohms/km @ 20 Deg C: 0.0601
AC Resistance in ohms/km @ 70 deg C: 0.073
Reactance @ 50Hz in ohms/km : 0.086
Max Current in Air: 465A
2c 400Sq. mm:
DC Resistance in ohms/km @ 20 Deg C: 0.047
AC Resistance in ohms/km @ 70 deg C: 0.059
Reactance @ 50Hz in ohms/km : 0.086
Max Current in Air: 530A
Request help on follow Questions:
1) What will be the voltage drop if 2c 300 Sq. mm cable is used?
2) What will be the voltage drop in 2c 400 Sq. mm cable is used?
3) Will laying parallel multiple cables reduce the voltage drop?
4) Does Sq. mm size imply size of each core or it indicates the total cross section area comprising of both cores?
Thanks
TPS
