Application Notes on Setting Cooper Form 3A Recloser Controllers
I. Recloser Models
This is a summary of the data a CAPE user must provide for the Cooper Power SystemsForm 3A recloser controller.
Typical STYLE used in CAPE is as follows:
Style Properties
Form 3A#KMEB General purpose controller style for model Form 3A, suitable forall Cooper or McGraw-Edison reclosers designed to be used withan electronic controller.
For details of the recloser, refer to the description in the Cooper Publication 280-75.
II. Recloser Elements
The recloser contains phase and ground overcurrent elements, with separate settingspossible for quick and delayed trip.
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
III. Overcurrent Timing Curves
There are a number of timing curves available, all of which are included in the text tapranges named “ME Curves (GR)” and “ME Curves (PH)”. The following table lists thecurves included:

IV. Recloser Taps
When placing a recloser, set the following taps. Only the settings with Internal Nameshown in bold are actually used in the Program Model for this recloser.

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
If there are duplicates from other reclosers in the same LZOP, you may add the prefix"FORM3A_" , e.g. "FORM3A_GND_TCC1".
The LZOP LOGIC (e.g. FORM3A_TRIP) for all elements is
PHS_TCC1 OR PHS_TCC2 OR GND_TCC1 OR GND_TCC2
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
