Incomer cable sizing from Aux. Trafo to ACDB ( Q101, Q102,Q103 )

Cable To : ACDBSystem Voltage (V) = 220 VConnected Load (S) = 2000000 VACurrent through the feeder =

Cable size selected 6 x 1C x 630and 3 x 1C x 630

Derating Factors

Type of Cable laying : Trefoil touching in cable trench= 0.91 (As Per Riyadh cable Co. catalouge table 10)= 0.87 (As per TES-P-119.29 Cl. 7.1.7.a.i)

Net derating Factor (K) = 0.79Derated current carrying capacity of the cable =

Calculation of Voltage Drop

= 0.042Unit reactance of the cable (X) = 0.091Total route length of the cable (L) = 13.5 m

= 0.0001 W= 0.0002 W 31.79= 0.85= 0.53== 1.71 V

% Voltage drop == 0.78 %

Permissible Voltage drop = 0.8 %

The actual voltage drop is lesser than the permissible voltage drop --> 2

Check for Short circuit withstand capacity of the cable

The conductor size is checked for short circuit with the following formulae:

t = Duration of Short circuit = 1 second

S = Cross sectional area of the cable = 630

Substituting in the above equation, we get= 90090 A

= 90 KA, for one secondRated fault withstanding current at the Tranformer = 80.325 KA

Short circuit current withstand capacity of the cable is higher than that at the Tranformer -->3

Unit AC resistance of the cable @ 90oC (R) W / kmW / km
