63511kV CopperAluminium 89 12722kV CopperAluminium 1011 1933kV.

. Just divide by 1000. V drop V I wire A R wire Ωkm 1000 mkm 2. Voltage dropvoltage drop amperemeter x length x current.

The line to line voltage drop V in volts V is equal to square root of 3 times the wire current I in amps A times one way wire length L in feet ft times the wire resistance. Correction factor k1 089 group factor for ground k4 100 cable laying depth factor k3 096 soil correction factor for air k2 105 total derating factor 090 cable calculation conductor. It is still IZ.

P Total Power in KVA L Total Length of Line. Once you get all the above data the voltage drop can be calculated as follows. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How YouTube works Test new features Press Copyright Contact us Creators.

Required Cable Size mm2 Voltage Drop volts. So suppose you are delivering say 50KW of. Calculate Your Voltage Drop Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run.

Cable manufacture should be able to provide you with the reactance and resistance values of the cable and use those values. Voltage Regulation for 11KV 22KV 33KV Overhead Line Voltage Regulation 106 x P x L x PF LDF x RC x DF Where. Cable Sales Phone 1300 CABLES.

Take the value of the current flowing through the cable. The following calculator computes the resistance inductance inductive reactance capacitance charging current and. At full load current I fl 361 A at 085 power factor the cable voltage.

The cable size it determined by the wattage it delivers and therefore the ampacity because P VI or in 3ph circuits P sqrt3VI therefore I Psqrt3V. Allowable Voltage Drop Cable Length m Calculate Min. Where I is the fault short circuit current in kA t is the time of fault and K is a constant.

V D 173 x 855 x 01964 x 09. Set Load to 4x rated powercurrent for motor applications. Therefore the voltage drop on this cable is.

Multiply twice the length of the cable with the quantity. Up to 3 cash back Here is a formula A I x t K mm2. Head Office 207 Sunshine Road Tottenham Australia.

CurrentkARequired FieldNumeric value greater than 0DurationsRequired FieldRange value between 05 and 1Numeric value max 2 decimals greater than 0. So I KA t. Voltage drop Vd Consider a 100 m route length of cable with resistance and inductive reactance X L.

Use per phase values. Following is the step by step method to calculate voltage drop of the cable. When sizing conductors calculations.

Since there are 4 runs of cable total resistance and reactance will be divided by 4 accordingly. Eland Cables supplied a range of DNO-approved cables including 63511kV voltages for the UK distribution network operators UKPN SSE Western Power. Finally we can get the voltage drop by multiplying current times resistance times cable length by 2 because one way and back such so.
