Application Notes on Setting Cooper Form 4C Recloser Controllers

I. Recloser Models

This is a summary of the data a CAPE user must provide for the Cooper Power SystemsForm 4C recloser controller.

Typical STYLE used in CAPE is as follows:

Styles Properties

Form 4C#KME4C1111-1Form 4C#KME4C1111-2Form 4C#KME4C1111-3Form 4C#KME4C1111-4

General purpose controller styles for model Form 4C,suitable for use with all applicable Cooper or McGraw-Edison switchgear. Styles are provided for setting groups 1,2, 3, and 4, respectively.

For details of the recloser, refer to the description in the Cooper Publication S280-77-4.

II. Recloser Elements

The recloser contains phase and ground overcurrent elements, with separate settingspossible for quick and delayed trip, and a Sensitive Earth Fault (SEF) element.

Element Description

Ground TCC1 Ground operation – quick trip

Ground TCC2 Ground operation – delayed trip

Phase TCC1 Phase operation – quick trip

Phase TCC2 Phase operation – delayed trip

SEF Sensitive Earth Fault

III. Overcurrent Timing Curves

There are a number of timing curves available, 21 of which are available at one time in oneof four selected groups. These are included in the four text tap ranges named “F4C Group1”, “F4C Group 2”, “F4C Group 3”, and “F4C Group 4”. The CAPE database is not able tosimulate an actual switching from one group to another as the actual controller doesthrough the tap value “TCC Group”. Therefore, a Form 4C style has been developed foreach of the four TCC groups. For TCC Group n (where n = 1, 2, 3, or 4), select style Form4C#KME4C1111-n.

The following table lists the curves included in each group:

V. Element Settings

On the element forms, set only the necessary contact logic codes; other settings are takenfrom the common taps. You can also change the settings from CAPE CG using the forms orusing DRAG_CURVE. The new common taps are computed automatically from theelement settings.

VI. Contact Logic

Suggested contact logic codes:

Element Contact Logic CodeGround TCC1 GND_TCC1

Ground TCC2 GND_TCC2

Phase TCC1 PHS_TCC1

Phase TCC2 PHS_TCC2

SEF SEF_TCC

If there are duplicates from other reclosers in the same LZOP, you may add the prefix"FORM4C_" , e.g. "FORM4C_GND_TCC1".

The LZOP LOGIC (e.g. FORM4C_TRIP) for all elements is

PHS_TCC1 OR PHS_TCC2 OR GND_TCC1 OR GND_TCC2 OR SEF_TCC

To prevent an element from tripping the logical breakers in its local zone of protection(LZOP), omit its contact-logic code from this expression. For ground elements alone, theexpression would be:

GND_TCC1 OR GND_TCC2 OR SEF_TCC
