Inverse Overcurrent (51) Protection

BE1-11

g

Unbalance Mode

Unbalance mode provides unbalanced current protection. Two methods are available to calculate
unbalanced current. The first method is based on the negative-sequence current divided by the positive-
sequence current while the second method is based on the average current. The calculation method must
be specified on the System Parameters, Sensing Transformers screen in BESTCOMS

Plus

. Refer to the

Configuration

chapter for more information.

CT Source

The CT Source setting configures an inverse overcurrent element to monitor CT circuit 1 or CT circuit 2
on protection systems equipped with two sets of CTs. CT circuit 1 terminals are designated D1 (IA1)
through D8 (IG1) and CT circuit 2 terminals are designated F1 (IA2) through F8 (IG2). For an illustration,
refer to the

Terminals and Connectors

chapter.

Direction

An inverse overcurrent element can be configured for forward or reverse tripping. Refer to the

Directional

Overcurrent (67) Protection

chapter for more information.

Directional Source

The Directional Source setting selects the directional element (67-1 or 67-2) to be used when making
directional decisions on protection systems equipped with two sets of CTs. The CT source of the
directional source selection (67-1 or 67-2) should match the CT source selection of the inverse
overcurrent (51) element.

Timings

Each inverse overcurrent element has a Curve setting. The following paragraphs describe the available
timing curves. The user can select integrating reset timing to make the protective element use integrated
reset and emulate an electromechanical induction disk reset characteristic.

Standard Curves

There are 22 standard curves available including standard inverse, short inverse, moderately inverse,
long inverse, very inverse, and extremely inverse. Refer to the

Time Curve Characteristics

chapter for

specific information on each curve.

Programmable Curves

An available programmable curve can be used to create a custom curve by selecting coefficients in the
inverse time characteristic equation. When inverse time overcurrent characteristic curve P is selected, the
coefficients used in the equation are those defined by the user. Inverse overcurrent characteristics for trip
and reset programmable curves are defined by Equation 14 and Equation 15. These equations comply
with IEEE Std C37.112-1996 -

IEEE Standard Inverse-Time Characteristic Equations for Overcurrent

Relays

. Definitions for these equations are provided in Table 37. The curve-specific coefficients are

defined for the standard curves as listed in the

Time Curve Characteristics

chapter.
