Ground Overcurrent

The

Ground Overcurrent

element trips the IntelliRupter fault interrupter when the

computed residual of the three-phase elements exceeds the pickup value for the time
value set by the

Inverse Curve or Definite Time

settings.

Ground Check box—

Select to configure this element.

Inverse Segment—

Select from the drop-down list of inverse curve names or select

the

None

setting. When the

None

setting is selected, only the

Definite Time

settings

will be used.

Min. Trip—

This is the current (in primary amperes) at which the inverse curve begins

timing. (Range: 6-16,000; Step: 1) The stated maximum is for 15-kV IntelliRupter fault
interrupters; 27-kV and 38-kV are limited to 12,500 amps maximum.

Min. Time—

This is the time (in seconds) defining the fastest response of the inverse

curve portion of the TCC curve. (Range: 0.000-100.000; Step: 0.001)

Time Mult—

This is the time modifier for the inverse curve. (Range: 0.01-15.00; Step: 0.01)

Time Adder—

This is the time modifier for the inverse curve. (Range: -10.000-100.000;

Step: 0.001)

Low Cutoff—

This is the current (in primary amperes) at which the TCC curve begins

timing. This value must be equal to or greater than the lowest pickup value of the inverse
curve, the

Definite Time 1

element, and the

Definite Time 2

element. (Range: 6-16,000;

Step: 1) The stated maximum is for 15-kV IntelliRupter fault interrupters; 27-kV and 38-kV
are limited to 12,500 amps maximum.

Reset—

Select the reset method for the inverse curve from the drop-down list:

D/T

(Definite Time) or

E/M

(Electromechanical) mode.

Reset Time—

If the

Definite Time

reset mode is selected, enter the time delay for the

reset (in seconds). (Range: 0.000-600.000; Step: 0.001)

Definite Time 1 Min. Trip—

This is the current (in primary amperes) at which the

Definite Time 1

element picks up. (Range: 6-16,000; Step: 1) The stated maximum is

for 15-kV IntelliRupter fault interrupters; 27-kV and 38-kV are limited to 12,500 amps
maximum.

Definite Time 1 Min. Time—

This is the time delay (in seconds) after which the

Definite

Time 1

element trips. (Range: 0.000-600.000; Step: 0.001)

Definite Time 2 Min. Trip—

This is the current (in primary amperes) at which the

Definite Time 2

element picks up. (Range: 6-16,000; Step: 1) The stated maximum is

for 15-kV IntelliRupter fault interrupters; 27-kV and 38-kV are limited to 12,500 amps
maximum.

Definite Time 2 Min. Time—

This is the time delay (in seconds) after which the

Definite

Time 2

element trips. (Range: 0.000-600.000; Step: 0.001)
