.Buildings.Electrical.Transmission

Information

This package contains cables that can be used to represent a line in a electric grid. The package contains several functions and records to parametrize cables either using default values or values from commercial cables.

The package Buildings.Electrical.Transmission.Grids contains models of electrical networks.

Commercial cables

The package contains several low voltage and medium voltage cable with pre-defined physical and geometrical properties like characteristic resistances and diameters. There are different conventions to measure the cables.

Cross-sectional area

A measure of cross-sectional area in square mm. E.g. 50 mm2 wire has a nominal circula area of 50 mm2 and a diameter of 7.98 mm.

AWG (American Wire Gauge)

A measure of wire thickness (which also dictates cross-sectional area, and for a given material, ampacity). E.g. 24 AWG wire has a nominal diameter of 0.0201 in or 0.511 mm.

kcmil (thousand of Circular Mils)

kcmil is an abbreviation for thousands of circular mils, an old measurement of wire gauge. 1 kcmil = 0.5067 square millimeters. A mil is 1/1000 inch. A wire 200 mils in diameter is 40 kcmil. kcmil is generally used for very large-diameter wire. Most wires use AWG.
