1-4 General Information BE1-CDS220
Transformer Monitoring
•
Transformer through-fault duty statistics are recorded including number of through faults,
accumulated through-fault (
It or I
2
t
), and maximum through-fault (
It or I
2
t
). The through-
fault current measurement is assignable to any of the current input circuits.
•
Each of these conditions can be set to alarm.
Breaker Monitoring
•
Breaker statistics are recorded for a single breaker. They include the number of operations,
accumulated interrupted
I
or
I
2
, and breaker time to trip. This function is associated with the
current input circuit assigned to the breaker failure function block.
•
Each of these conditions can be set to alarm.
Trip Circuit Monitoring
•
A trip circuit monitor function is provided to monitor the trip circuit of a breaker or lockout relay for
loss of voltage (fuse blown) or loss of continuity (trip coil open).
•
Additional trip or close circuit monitors can be implemented in BESTlogic using additional inputs,
logic timers, and programmable logic alarms.
Fault Reporting
•
Fault reports consist of simple target information, fault summary reports, and detailed
oscillography records to enable the user to retrieve information about disturbances in as much
detail as is desired.
•
Oscillography memory can be partitioned into 6 to 16 records (6 to 32 records with enhanced
recording option, Load Profile option Y).
•
The relay records and reports oscillography data in industry standard IEEE, COMTRADE format
to allow using any fault analysis software.
Sequence of Events Recorder
•
A 255 event sequence of events recorder (SER) is provided that records and time stamps all
inputs and outputs to the relay as well as all alarm conditions monitored by the relay. Time
stamps are to the nearest quarter cycle resolution.
•
I/O and Alarm reports can be extracted from the records as well as reports of events recorded
during the time span associated with a specific fault report.
Alarm Function
•
The relay includes extensive self diagnostics. Fatal relay trouble alarms are not programmable
and are dedicated to OUTA and the relay trouble LED on the front of the relay.
•
Additional relay trouble alarms and all other alarm functions are programmable for major or minor
priority. Programmed alarms are indicated by major and minor alarm LEDs on the front of the
relay. The major and minor alarm points can also be programmed to any output contact including
OUTA.
•
The optional HMI provides local annunciation of programmed alarm conditions.
•
Active alarms can be read and reset from the optional HMI or from the communications ports. A
historical sequence of events report of alarms with time stamps as to when each alarm occurred
and cleared is also available from the communications ports.
•
Twenty-eight alarm conditions are available to be monitored including user definable logic
conditions using BESTlogic.
Version Report
•
The version of the embedded software (firmware) is available from the optional front panel
interface HMI or the communications ports.
•
The unit serial number and style number is also available from the communications ports.
BESTlogic Programmable Logic
•
Each of the protection and control functions in the BE1-CDS is implemented in an independent
function that is equivalent to its single function, discrete device counterpart so that it is
immediately familiar to the protection engineer. Each independent function block has all of the
inputs and outputs that the discrete component counterpart might have. Programming BESTlogic
