The formulas stated for alternating and three-phase current do not give any consideration to the inductive resistance.

Example: What is the current consumptio of an alternating current motor of 1.9kW at cos = 0.77 and an efficiency of 79%?

The voltage is230V, 50 Hz.

This resistance is a function of the distance of the individual conductors between one another.

Technical data/Calculations

Permissable three-phase cable loading at 5% voltage drop Representation: I = F(L) and I = F(P) cos = 0.82

Example: A power of 70 kW is to be transmitted across a distance of L = 450 m. The function I = F(P) gives us 70 kW  130 A (mixed users).

The function I = F(L) provides the cable crosssection of 95mm².

A length of 500m would already require a cable of 120mm² to ensure that the voltage loss and therefore also the power loss would be in an acceptable and economical range.

30 | P a g e T e c h n i c a l D a t a

Representation: I = F(L) shows that, for example, for 95mm² the permissable fuse of 200A determines the load limit up to L = 300m, i.e. Uv < 5%.

From 300m the cross-section can no longer be fully utilized.
