Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions

Manual Close Delay

Manual Close Delay provides a delay from the time that the manual CLOSE button is pushed to the time the manual close operation is performed.

The delay is programmable from 0 to 60 seconds in 1 second increments. A programmed delay value can be overridden for immediate closing by pressing the CLOSE button a second time.

An active Manual Close Delay can be canceled by pressing 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 performed on-line (updates every 30 seconds) or demand integrated to user-specified time values. The Total Harmonic Distortion (THD) for current and voltage is available from the operator panel display (Figure 12) while complete 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

500events 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 occurrences 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 ability 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.
