## WireData

This class of data defines the raw conductor data that is used to compute the impedance for a line geometry.

Note that you can use whatever units you want for any of the dimensional data – be sure to declare the units. Otherwise, the units are all assumed to match, which would be very rare for conductor data. Conductor data is usually supplied in a hodge-podge of units. Everything is converted to meters internally to the DSS

Rdc= dc Resistance, ohms per unit length (see Runits). Defaults to Rac if not specified.

Rac= Resistance at 60 Hz per unit length. Defaults to Rdc if not specified.

Runits= Length units for resistance: ohms per {mi|kft|km|m|Ft|in|cm } Default=none.

GMRac= GMR at 60 Hz. Defaults to .7788*radius if not specified.

GMRunits= Units for GMR: {mi|kft|km|m|Ft|in|cm } Default=none.

Radius= Outside radius of conductor. Defaults to GMR/0.7788 if not specified.

Capradius- Equivalent conductor radius for capacitor calcs. Specify this for bundled conductors. Defaults to same value as radius.

Radunits= Units for outside radius: {mi|kft|km|m|Ft|in|cm } Default=none.

Normamps= Normal ampacity, amperes. Defaults to Emergency amps/1.5 if not specified.

Emergamps= Emergency ampacity, amperes. Defaults to 1.5 * Normal Amps if not specified.

Diam= Diameter; Alternative method for entering radius.

Like= Make like another object of this class:

For bundled conductors, you define an equivalent conductor with

GMRB = [N(GMRC)A(N-1)]1/N

Where

N = number of conductors in the bundle

GMRC = GMR of each subconductor

A = bundle radius

For capacitive reactance calculations, the effective radius (Capradius) of the bundle is

rB = (NrAN-1)1/N

Where

N = number of conductors in the bundle

r = radius of each conductor

A = bundle radius

When the bundle size is specified by the bundle spacing (distance between adjacent conductors in the bundle, S)

A = S / [2 sin(π/N)] for N>1

A = 0 for N=1 (recall that 00 = 1)
