The properties of the Fuse object are as follows:


Property

Description

(1) MonitoredObj

Full object name of the circuit element, typically a line, transformer, load, or

generator, to which the Fuse is connected. This is the "monitored" element.

There is no default; must be specified.

(2) MonitoredTerm

Number of the terminal of the circuit element to which the Fuse is connected. 1 or 2, typically. Default is 1.

(3) SwitchedObj

Name of circuit element switch that the Fuse controls. Specify the full object name.Defaults to the same as the Monitored element. This is the "controlled" element.

(4) SwitchedTerm

Number of the terminal of the controlled element in which the switch is

controlled by the Fuse. 1 or 2, typically. Default is 1. Assumes all phases of the element have a fuse of this type.

(5) FuseCurve

Name of the TCC Curve object that determines the fuse blowing. Must have been previously defined as a TCC_Curve object. Default is "Tlink". Multiplying the current values in the curve by the "RatedCurrent" value gives the actual current.

(6) RatedCurrent

Multiplier or actual phase amps for the phase TCC curve. Defaults to 1.0.

(7) Delay

Fixed delay time (sec) added to Fuse blowing time determined from the TCC curve. Default is 0.0. Used to represent fuse clearing time or any other delay.

(8) Action

{Trip/Open | Close} Action that overrides the Fuse control. Simulates manual control on Fuse "Trip" or "Open" causes the controlled element to open and lock out. "Close" causes the controlled element to close and the Fuse to reset.

(9) basefreq

Base Frequency for ratings.

(10) enabled

{Yes|No or True|False} Indicates whether this element is enabled.
