Name

Default

Units

Description

1

NConds

integer

0

Number of conductors in this geometry. Triggers memory allocations. Define first!

2

NPhases

integer

0

Number of phases. All other conductors are considered neutrals and might be reduced out.

3

Cond

integer

Set this = number of the conductor you wish to define.

4

Wire

string
(WireData name)

Code from WireData. MUST BE PREVIOUSLY DEFINED. no default.
Specifies use of Overhead Line parameter calculation,
Unless Tape Shield cable previously assigned to phases, and this wire is a neutral.
Redundant with Wires

5

X

real
(on array)

x coordinate.

6

H

real
(on array)

Height of conductor.

7

Units

string
(from enum. Length Unit)

Units for x and h. Initial default is “ft”, but defaults to last unit defined

8

NormAmps

real

0.0

Normal ampacity, amperes for the line. Defaults to first conductor if not specified.

9

EmergAmps

real

0.0

Emergency ampacity, amperes. Defaults to first conductor if not specified.

10

Reduce

boolean

False

Reduce to Nphases (Kron Reduction). Reduce out neutrals.

11

Spacing

string
(LineSpacing name)

Reference to a LineSpacing for use in a line constants calculation.
Alternative to x, h, and units. MUST BE PREVIOUSLY DEFINED.
Must match “nconds” as previously defined for this geometry.
Must be used in conjunction with the Wires property.

12

Wires

array of strings
(WireData names)

Array of WireData names for use in a line constants calculation.
Alternative to individual wire inputs. ALL MUST BE PREVIOUSLY DEFINED.
Must match “nconds” as previously defined for this geometry,
unless TSData or CNData were previously assigned to phases, and these wires are neutrals.
Must be used in conjunction with the Spacing property.

13

CNCable

string
(CNData name)

Code from CNData. MUST BE PREVIOUSLY DEFINED. no default.
Specifies use of Concentric Neutral cable parameter calculation.
Redundant with Wires

14

TSCable

string
(TSData name)

Code from TSData. MUST BE PREVIOUSLY DEFINED. no default.
Specifies use of Tape Shield cable parameter calculation.
Redundant with Wires

15

CNCables

array of strings
(CNData names)

Array of CNData names for cable parameter calculation.
All must be previously defined, and match “nphases” for this geometry.
You can later define “nconds-nphases” wires for bare neutral conductors.
Redundant with CNCable

16

TSCables

array of strings
(TSData names)

Array of TSData names for cable parameter calculation.
All must be previously defined, and match “nphases” for this geometry.
You can later define “nconds-nphases” wires for bare neutral conductors.
Redundant with TSCable

17

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. Defaults to first conductor if not specified.

18

Ratings

array of reals

[0.0]

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. Defaults to first conductor if not specified.

19

LineType

string
(from enum. Line Type)

oh

Code designating the type of line.
OpenDSS currently does not use this internally. For whatever purpose the user defines.

20

Like

string
(LineGeometry name)
deprecated

Make like another object, e.g.:

New Capacitor.C2 like=c1 …
