Description

1

MonitoredObj

string
(CktElement name)

Full object name of the circuit element, typically a line, transformer, load, or generator, to which the Recloser’s PT and/or CT are connected. This is the “monitored” element. There is no default; must be specified.

2

MonitoredTerm

integer

1

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

3

SwitchedObj

string
(CktElement name)

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

4

SwitchedTerm

integer

1

Number of the terminal of the controlled element in which the switch is controlled by the Recloser. 1 or 2, typically. Default is 1.

5

NumFast

integer

1

Number of Fast (fuse saving) operations. (See “Shots”)

6

PhaseFast

string
(TCC_Curve name)

a

Name of the TCC Curve object that determines the Phase Fast trip. Must have been previously defined as a TCC_Curve object. Default is “A”. Multiplying the current values in the curve by the “phasetrip” value gives the actual current.

7

PhaseDelayed

string
(TCC_Curve name)

d

Name of the TCC Curve object that determines the Phase Delayed trip. Must have been previously defined as a TCC_Curve object. Default is “D”.Multiplying the current values in the curve by the “phasetrip” value gives the actual current.

8

GroundFast

string
(TCC_Curve name)

Name of the TCC Curve object that determines the Ground Fast trip. Must have been previously defined as a TCC_Curve object. Default is none (ignored). Multiplying the current values in the curve by the “groundtrip” value gives the actual current.

9

GroundDelayed

string
(TCC_Curve name)

Name of the TCC Curve object that determines the Ground Delayed trip. Must have been previously defined as a TCC_Curve object. Default is none (ignored).Multiplying the current values in the curve by the “groundtrip” value gives the actual current.

10

PhaseTrip

real

1.0

Multiplier or actual phase amps for the phase TCC curve.

11

GroundTrip

real

1.0

Multiplier or actual ground amps (3I0) for the ground TCC curve.

12

PhaseInst

real

0.0

Actual amps for instantaneous phase trip which is assumed to happen in 0.01 sec + Delay Time. Default is 0.0, which signifies no inst trip.

13

GroundInst

real

0.0

Actual amps for instantaneous ground trip which is assumed to happen in 0.01 sec + Delay Time. Default is 0.0, which signifies no inst trip.

14

Reset

real

15.0

s

Reset time for Recloser.

15

Shots

integer

4

Total Number of fast and delayed shots to lockout. Default is 4. This is one more than the number of reclose intervals.

16

RecloseIntervals

array of reals

[0.5, 2.0, 2.0]

Array of reclose intervals. Default for Recloser is (0.5, 2.0, 2.0) seconds. A locked out Recloser must be closed manually (action=close).

17

Delay

real

0.0

s

Fixed delay time added to Recloser trip time. Used to represent breaker time or any other delay.

18

Action

string
(from enum. Action)

DEPRECATED. See “State” property
Redundant with State

19

TDPhFast

real

1.0

Time dial for Phase Fast trip curve. Multiplier on time axis of specified curve.

20

TDGrFast

real

1.0

Time dial for Ground Fast trip curve. Multiplier on time axis of specified curve.

21

TDPhDelayed

real

1.0

Time dial for Phase Delayed trip curve. Multiplier on time axis of specified curve.

22

TDGrDelayed

real

1.0

Time dial for Ground Delayed trip curve. Multiplier on time axis of specified curve.

23

Normal

string
(from enum. State)

closed

Normal state of the recloser. The recloser reverts to this state for reset, change of mode, etc. Defaults to “State” if not specifically declared.

24

State

string
(from enum. State)

closed

Actual state of the recloser. Upon setting, immediately forces state of the recloser, overriding the Recloser control. Simulates manual control on recloser. Defaults to Closed. “Open” causes the controlled element to open and lock out. “Closed” causes the controlled element to close and the recloser to reset to its first operation.

25

BaseFreq

real

Hz

Base Frequency for ratings.

26

Enabled

boolean

True

Indicates whether this element is enabled.

27

Like

string
(Recloser name)
deprecated

Make like another object, e.g.:

New Capacitor.C2 like=c1 …
