Description

1

RDC

real

Ω/[length_unit]

WireData.rdc

2

RAC

real

Resistance at 60 Hz per unit length. Defaults to \(1.02 × Rdc\) if not specified.

3

RUnits

string
(from enum. Length Unit)

none

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

4

GMRAC

real

GMR at 60 Hz. Defaults to \(0.7788 × radius\) if not specified.

5

GMRUnits

string
(from enum. Length Unit)

none

Units for GMR.

6

Radius

real

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

7

RadUnits

string
(from enum. Length Unit)

none

Units for outside radius.

8

NormAmps

real

Normal ampacity, amperes. Defaults to \(EmergAmps / 1.5\) if not specified.

9

EmergAmps

real

Emergency ampacity, amperes. Defaults to \(1.5 × NormAmps\) if not specified.

10

Diam

real

Diameter; Alternative method for entering radius.
Redundant with Radius

11

Seasons

integer

Defines the number of ratings to be defined for the wire, to be used only when defining seasonal ratings using the “Ratings” property.

12

Ratings

array of reals

[-1.0]

An array of ratings to be used when the seasonal ratings flag is True. It can be used to insert
multiple ratings to change during a QSTS simulation to evaluate different ratings in lines.

13

CapRadius

real

Equivalent conductor radius for capacitance calcs. Specify this for bundled conductors. Defaults to same value as radius. Define Diam or Radius property first.
