Basler Electric BE1-700 - Manual (Page 15)

Voltage transformer circuit monitoring adds security by detecting problems in the voltage transformer
sensing circuits and preventing mis-operations of the 27P/127P, 47, 59P/159P.
Frequency Protection (BE1-700V)
There are six independent frequency elements. Each can be set for overfrequency or underfrequency
operation. Each can be individually set to monitor the frequency on the main three-phase voltage input or
the VX input.
Breaker Failure Protection (BE1-700C)
One breaker failure protection block (BF) provides programmable breaker failure protection.
Fuse Loss Protection (BE1-700V)
A fuse loss function protects against false tripping due to a loss of voltage sensing.
General Purpose Logic Timers
Two general purpose logic timers (62, 162) with six modes of operation are provided.
Setting Groups
Two setting groups allow adaptive relaying to be implemented to optimize BE1-700 settings for various
operating conditions. Automatic and external logic can be employed to select the active setting group.
Virtual Control Switches
BE1-700 virtual control switches include one virtual breaker control switch and two virtual 43 switches.
Trip and close control of a selected breaker can be controlled by the Virtual Breaker Control Switch (101).
The virtual breaker control switch is accessed locally from the front panel human-machine interface (HMI)
or remotely from the communication ports.
Additional control is provided by the two virtual switches: 43 and 143. These virtual switches are
accessed locally from the front panel HMI or remotely from the communication ports. Virtual switches can
be used to trip and close additional switches or breakers, or enable and disable certain functions.
Metering Functions
Metering is provided for all measured currents, voltages and frequency, and all derived neutral and
negative-sequence currents and voltages.
Reporting and Alarm Functions
Several reporting and alarm functions provide fault reporting, demand, breaker and trip circuit monitoring
as well as relay diagnostic and firmware information.
Relay Identification
Two free-form fields are provided for the user to enter information to identify the relay. These fields are
used by many of the reporting functions to identify the relay that the report is from. Examples of relay
identification field uses are station name, circuit number, relay system, purchase order, and others.
IRIG
A standard IRIG input is provided for receiving time synchronization signals from a master clock.
Automatic daylight saving time compensation can be enabled. Time reporting is settable for 12 or 24-hour
format. The date can be formatted as mm/dd/yy or dd/mm/yy.
General Status Reporting
The BE1-700 provides extensive general status reporting for monitoring, commissioning, and
troubleshooting. Status reports are available from the front panel HMI or communication ports.
Demand Reporting
Ampere demand registers monitor phase A, B, C, neutral and negative-sequence values. The demand
interval and demand calculation method are independently settable for phase, neutral and negative-
sequence measurements. Demand reporting records today's peak, yesterday's peak and peak since reset
with time stamps for each register.
Breaker Monitoring
Breaker statistics are recorded for a single breaker. They include the number of operations, fault current
interruption duty and breaker time to trip. Each of these conditions can be set to trigger an alarm.
