Form 6 microprocessor-based rack-mount recloser control
Metering
The control provides instantaneous and/or demand
metering with programmable integration intervals for the
followingfunctions:
Real and reactive power for each phase and total,
including directional, on an individual phase basis.
Demand currents on a per phase basis.
Instantaneous currents, including ground current.
Instantaneous voltage on a per phase basis.
Instantaneous frequency.
Positive, negative, and zero sequence voltages.
Instantaneous power factor on a per phase basis.
Metering settings to include demand interval, and alarm
thresholds for current, single-phase kW, three-phase kW,
single-phase kvar, and three-phase kvar.
Event recorder
The Form 6 control contains capabilities to perform
Sequence of Events time-stamping for up to 33 event
types. Sixteen additional inputs can be user-defined through
the Idea Workbench.
Factory-defined event types include:
Overcurrent Protection Trip
External Trip
Non-Reclose Trip
External Close
Lockout
Reset
The Event Recorder maintains a minimum of 90 event
records. The last 25 events are viewable on the front
panel LCD display. Refer to Service Information S280-70-4
(ProView 4.X.X) or S280-70-21 (ProView 5.X.X) Form 6
Control Programming Guide for additional information.
Recloser duty monitor
The Form 6 recloser control software is equipped with
a Recloser Interrupting Duty Monitor. The Duty Monitor
accumulates the summation of I
1. 5
for all interrupted
currents on each interrupter. This feature permits
programmable entries to preset the duty of an existing
recloser. The recloser duty monitor displays interrupting duty
in percent of duty used. If the duty cycle monitor exceeds
100%, the recloser should be examined for maintenance.
Discrete SCADA communications
The control provides five configurable output status contacts
and three configurable input control contacts as standard.
Each status contact is configurable using graphical interface
software to combine status functionality along with Boolean
algebra. Default output status contacts are: Lockout,
Recloser Open, Recloser Closed, Ground Trip Block, and Hot
Line Tag. One output status contact is a solid state output
(SS1) with a pickup time no longer than twomilliseconds.
The control also provides a minimum of three configurable
input control contacts. Each control contact is configurable
using ProView application software. Contacts accept a
whetting voltage range of 9 VDC - 290 VDC, 7 VAC - 265
VAC. Each digital input is configured for either a momentary,
maintained, or maintained with precedence contact. Default
input control contacts are: Supervisory Trip and Lockout,
Supervisory Close, and Remote Trip and Lockout.
A Discrete Interface Board is also available as an accessory
to provide an additional eight output status contacts and
eight input control contacts. The expansion I/O board is
completely user-configurable.
TCC Editor II
Coordination and actual time current modifications are
available with a graphic interactive TCC Editor or similar
graphical software.
The TCC Editor II includes a complete database of standard
recloser industry time current curves (TCC), both ANSI and
IEC types, along with the ability to customize the TCCs with
multipliers, constant time adders, or minimum response time
adders. Also, the user is able to derive their own specific TCC
through data point entry. Each modified time current curve can
be identified with a user-customized name and is selectable
for configuring the control. The grid and format for presenting
the TCCs has a user-adjustable scale, including the option of
presenting multiple TCCs in various user-configured colors.
Oscillography
Oscillography is provided to present current and voltage
waveforms, along with protection element and recloser
response status changes. Filtered and unfiltered data are
provided for viewing.
The recorded values are super-imposed on the protection
scheme, and the state or value at any point in the scheme is
displayed. The user has the capability to move through the
event and watch the response of every function. All analog
signals, digital inputs, and contact outputs are monitored.
Analog oscillography is displayed at 16 samples per cycle.
Oscillographic data is recorded to analyze multiple
events during a permanent fault or other event type. The
oscillographic data shows two cycles before the trigger
point and eight cycles after the trigger point (default).
ote:N The configuration settings are programmable.
Oscillography automatically initiates trigger points for the
following functions:
Above Minimum Trip for Phase, Ground, and Sensitive
Ground Fault
Single and Three-Phase Overvoltage
Single and Three-Phase Undervoltage
