CEC Voltage Drop

[timm33333]

I have question about Canadian voltage drop calculations. CEC Table D3 is limited in scope, so I guess it is better to calculate voltage drop using the impedance of the cables. NEC Table 9 gives the resistance and reactances of cables, but CEC does not have a table like this. In NEC the general practice is to calculate voltage drop using both resistance and reactance of the cable. However Note 1 of CEC table D3 states that inductive reactances are not utilized in voltage drop calculations. It looks that it is normal in Canada to do the voltage drop calculations based on AC resistance only.

So if I have to calculate the voltage drop for 3-Phase multi-conductor Teck-90 cable of 1000V insulation at 40C ambient, can I do the calculations based on the AC resistance values at 90C operating temperature given in the Anixter table (as attached here) ?

it's better that the resistance and reactances are all be involved in the calculation
