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 15) 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/Triple-Single control interface software to program the
activation time and time-current characteristics applicable
for 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.
Alarms
Status and data alarms are available for many control
parameters such as voltage and current thresholds. Data
alarm function compares metered data to user-pro-
grammed alarm high and low limits and issues an alarm of
user-specified priority if limits are exceeded. The status
alarm function monitors status and issues an alarm of
user-defined priority when the user-programmed alarm
conditions are met. The alarms are reported via commu-
nication ports and can be configured to trigger a data pro-
file and event record. Alarms do not affect the protection
functions of the control.
Status alarms are included for Modes A, B, and C as well
as the following status alarms for each phase of the Kyle
Type NOVA-TS Triple Single recloser:
• Open • Retry Fail
• Closed • Open Fail
• Lockout • Neither Open or Closed
• Close Retry Active • Yellow Handle Active
• Close Fail
Fault Location
Fault Location provides an approximate distance of a fault
from the the Form 5/Triple-Single control. The distance is
based on the current fault magnitude, the type of fault,
and system parameters entered by the user. The LCD dis-
play (Screen 38) identifies the estimated distance in miles
or kilometers (km) from the control.
The fault location algorithm performs an impedance cal-
culation based on:
• Single-phase to ground fault
• Phase-to-phase fault
• Double-line to ground fault
• Three-phase fault
This information is recorded as an event in the control
Event Recorder for retrieval. The fault location algorithm
does not require voltage sensing. If the location cannot be
determined, no event is recorded and dashes are dis-
played on the LCD screen.
Setting the parameters for Fault Location is done through
the interface software. The user enters line impedance
parameters and system voltage information into the soft-
ware via the Protection Profile menu. See Figure 16.
