GENERAL INFORMATION
DESCRIPTION
BE1-DFPR Distribution Feeder Protection Relays are microprocessor controlled devices with
communications that provide complete real time protection, monitoring, control, and instrumentation for
distribution circuits. In summary, it is an integrated feeder supervision system. DFPR relay communication
provides for collection of real time operational data on both protected distribution circuits and controlled
circuit breakers. Communication also provides fault data and distribution circuit status to a local or remote
location, and allows the user to change the settings or select relay predefined conditional settings to meet
existing operating system conditions as they occur.
FUNCTIONS
DFPR relay multiple functions provide protection, control, data processing, communication, set-up
provisions, and test provisions. These functions are expanded and listed in the following paragraphs.
Protection
Three-phase and neutral overcurrent.
Breaker failure.
Undervoltage and Overvoltage for each phase.
Frequency tripping/restoration.
Control
Multiple shot reclosing (4-shot).
Reclosing may be controlled with external inputs.
Accepts breaker, trip and close inputs.
Protection may be adapted to system conditions.
Data Processing
Measures watts, var, voltamperes, power factor, frequency, volts, or amperes.
Calculates present and stores minimum and maximum demand values.
Measures energy accumulation in watt hours and var hours.
Accumulates data on breaker duty.
Stores fault/event reports.
Output contacts provide status information for SCADA.
Communications
Menu driven operation.
Front and rear panel RS-232 ports.
Uses terminal or PC with off-the-shelf software.
Optional RS-485 rear port supporting special application protocols.
Set-up and Test Provisions
Standard connection/test plugs for testing in the case.
Test module for control inputs (option).
Test unit is available to simplify testing.
Built-in self-checking capabilities.

FEATURES
Each DFPR relay function has many different features. These features are also listed in the following
paragraphs and elaborate on the expanded functions.
Protection Features
Programmable integrating reset characteristics available for 51 functions.
Current and voltage sensing elements attenuate offsets and harmonics.
Different time overcurrent curves may be selected for phase and neutral.
Instantaneous overcurrent elements are provided for phase and neutral.
Fixed time overcurrent elements are provided for phase and neutral.
Tripping elements and the response of the reclosing section may be set for normal, AUX 1 (cold
load), AUX 2 (emergency), AUX 3 and AUX 4 settings by control inputs.
Inadditiontothemaintrippingoutputs,anindependenttripoutputmaybeprogrammedtooperate
on any of the protective functions.
Control inputs are provided to block all fixed time overcurrent elements and/or the neutral fixed
time and neutral time overcurrent elements.
The breaker failure element may be initiated by any protective tripping function or a supervisory
trip.
Abreakerfailalarm contact isprovidedtoindicatebreakerproblems that occurbeforethebreaker
fail function is actually caused to operate.
Zone sequence coordination provided.
Control Features
The reclosing function includes two programmable close outputs, inputs for initiate, drive-to-
lockout, and enabling or disabling reclosing.
The reclosing section of the relay is deactivated to prevent pumping when the breaker is tripped
or closed through one of the control inputs.
An output is provided to block the load tap changer on the substation transformer or voltage
regulator during a fault clearing or restoration process.
Overcurrent protective functions may be adapted through BT1 and BT2 control inputs.
Programmable inputs available for control features.
Data Processing Features
Data is formatted to display information in logical groups on computer or terminal.
Demand values are calculated for phase currents, watts, var, and voltamperes for intervals from
one to sixty minutes.
Energy accumulation in watt hours, var hours, and the number of hours since last reset are
calculated and stored.
Data stored on breaker duty includes number of operations and the sum of the I2or I values
interrupted.
Fault/event data is stored for up to 40 breaker operations.
Parameters being measured and/or stored may be displayed on the front panel.
Status outputs are provided for targets and reclose functions.
Battery backed-up clock provides date and time for reports.
Programmable alarm outputs available for alarm functions.
Communications Features
Front RS-232 port for observing menus and groups of data or set-up parameters via a portable

computer terminal.
Rear RS-232 port for connection to a communications link.
Communications provides access to set-up parameters, real time data, and stored information.
Settings upload and download.
Set-up and Test Provision Features
Access to the connection/test plugs is achieved by removing the left section of the front panel.
The optional test module provides the means to disconnect control inputs and apply test signals
through the test points.
Front panel display for reading data and setting parameters.
Menu driven procedures are user friendly.
