Manual Close Delay
Manual Close Delay provides a delay from the time that
the manual CLOSE button is pushed to the time the man-
ual close operation is performed.
The delay is programmable from 0 to 60 seconds in 1 sec-
ond increments. A programmed delay value can be over-
ridden for immediate closing by pressing the CLOSE
button a second time.
An active Manual Close Delay can be canceled by press-
ing the TRIP/LOCKOUT button.
The default setting has the feature disabled (0 seconds).
The RECLOSER CLOSED LED indicates the status of the
feature. See Figure 11.
Harmonic Analysis
Extensive harmonic analysis is performed by the Form 5
control for both currents and voltages. Analysis is per-
formed on-line (updates every 30 seconds) or demand
integrated to user-specified time values. The Total Har-
monic Distortion (THD) for current and voltage is available
from the operator panel display (Figure 12) while com-
plete analysis, including graphing capabilities, is provided
from the Form 5 interface software.
Reverse Power Flow
Feeder load monitoring is enhanced with the inclusion of
the power flow monitoring feature. When power flow from
the load to the source side of the recloser is detected, the
control illuminates an operator-panel indicator. Response
time to a reverse power condition is one second. An alarm
is also available for remote interrogation.
Note: Voltage sensor polarity must be correct for reverse
power flow to function properly.
Event Recorder
The Event Recorder maintains a log of operating events
for later readout and analysis by the user. Approximately
500 events can be stored in non-volatile memory. For
each event type, time of occurrence, and other relevant
information is stored. When the event recorder has
reached is capacity, the oldest event is deleted as a new
event is added.
Histograms
Demand metered voltages and currents can be reported
using the histogram tool. It displays the number of occur-
rences of a variable versus its value in between user-
defined minimum and maximum limits. Date and time are
recorded for the maximum and minimum demand values.
Data Profiler
A fully configurable data profiler is available which allows
the user to collect information by sampling demand data
at selectable intervals. These time-stamped values can
then be plotted to determine weekly load profiles, daily
harmonic disturbances or hourly voltage fluctuations. The
data profiler can provide more than 200 days of informa-
tion, depending upon configuration parameters.
Cold Load Pickup
Cold Load Pickup (CLPU) must be enabled through the
interface software (Figure 13) before it can be activated
remotely or from the CLOSE pushbutton on the operator
panel. The CLPU feature provides the user with the abil-
ity to alter protection for abnormal system conditions. It is
active for a programmable time interval which begins with
each manual close. Once this time elapses, protection
reverts back to the programmed sequence. Use the Form
5 control interface software to program the activation time
and time-current characteristics applicable to Cold-Load
Pickup.
Note: When CLPU is active, the control utilizes the Cold Load
Pickup TCC, reclose interval, operations to lockout, and
minimum trip settings in lieu of the normal protection
settings.
