Assumption Load Current (IDLF) = Ia x 120% = amps
AMPACITY DERATING :
Select a Cable Size for the requirement = 16 mm Ampacity = 98 Amperes 1 Set/s of Cable 4 Core/s Cable
Min. capacity of new cable (Id) = CAB.Ampacity x ( Correction Factor )
where :
Correction Factor for Thermal resist. of soil @ 1.2oC-m/W = (Saudi cable cat. for direct laid in ground)
(SAES-P-104, 12.3)
Correction Factor for ground temperature @ 40oC = (Saudi cable cat. for direct laid in ground)
(SAES-P-104, 12.2)
Correction Factor for depth of burial @ 0.60 in ground = (Saudi cable cat. for direct laid in ground)

Total Load kVA = kVA
Line Voltage (nominal) = volts phase = 3
Maximum Load Current (Ia) = (Load kVA x 1000) / ( 1.732 x V ) = amps
CABLE SIZING : (SAES-P-104, 12.1)
Assumption Load Current (IDL) = Ia x 120% = amps
AMPACITY DERATING :
Select a Cable Size for the requirement = 70 mm Ampacity = 229 Amperes 1 Set/s of Cable 4 Core/s Cable
Min. capacity of new cable (Id) = CAB.Ampacity x ( Correction Factor )
where :
Correction Factor for Thermal resist. of soil @ 1.2oC-m/W = (Saudi cable cat. for direct laid in ground)
(SAES-P-104, 12.3)
Correction Factor for ground temperature @ 40oC = (Saudi cable cat. for direct laid in ground)
(SAES-P-104, 12.2)
Correction Factor for depth of burial @ 0.60 in ground = (Saudi cable cat. for direct laid in ground)
(Cable Grouping Factor)
Correction Factor for grouping @ 0.15mtr. Flat formation = (Saudi cable cat. for direct laid in ground)
Id = 229 x (0.97 x 0.95 x 0.98 x 0.78) = Amps
CABLE SIZE CONCLUSION :
Cable Size : 70 mm
Cable Selected : 1 -SET, 4 /C - XLPE/SWA/PVC
Cable Ampacity : 161 amps therefore, cable derated ampacity is ok.
VOLTAGE DROP :
Z = (R x pf) + X x sin[arccos(pf)] (NEC Chapter 9, Table 9, Note 2)
Ze = (Z x L) / (n x 1000)
where : Z = Impedance
pf = Power Factor =
L = Cable Length = meters or feet
R = Resistance = ohms-neutral/KM (Saudi cable catalogue AC at 90C)
X = Reactance = ohms-neutral/KM (Saudi cable catalogue AC at 90C)
X = XL, since XCis negligible below 600V (NEC Table 9, 75C (167C))
n = no. of set/s of multi-core cables or ( for single core, n=1 ) = 1
Z = ( 0.343 x 0.85 ) + ( 0.0988 x sinarccos( 0.85 )) = ohms / KM
Ze = (0.3436 x 181) / (1 x 1000) = ohms
Voltage Drop (VD) = (Ia x Ze) x m = volts ( m = 1.732 for 3-Phase & m = 2 for Single Phase)%VD Required (SAES-P-100) = %
%VD = VD/VL x 100% = %
Voltage Reading at Junction = volts
TOTAL % VOLTAGE DROP = % Therefore, voltage drop ok.
