Disturbance Recording and Fault Locating Device DRL6600U
Product version: V8.30
11. Operation
Manual recording
Manual recording is available on the HMI.
Remote recording
Remote recording is available via MMS client
Local / remote reset
After disturbance recording, latched LED indicators
and digital outputs can be reset either locally or
remotely.
12. Monitoring
Analog signal sampling monitoring
DRL6600U acquires and stores data from current and
voltage channels with a sampling frequency of 10kHz.
Binary signal monitoring
Binary signal monitoring can display the status of
binary signals.
Disturbance report
Disturbance reports will be formed and saved when a
signal triggers recording or when there are fault
location results
The disturbance report will show automatically after
recording, and can also be manually checked.
The disturbance report will record the start time, subsite
number, subsite name, triggering name, triggering file
name, fault line, fault distance, fault phase, tripping
phase, and current and voltage RMS of one cyclic wave
both before and after the disturbance.

13. Basic IED functions
Self-supervision with internal event list
The
self-supervision
SELFSUPEVLST) will respond to internal system
events generated by the different internal self-
supervision functions. Internal events are saved in one
internal event list.
Self-supervision function
The build-in self-supervision function continuously
monitors the hardware and software operation status.
Once a disturbance or abnormality is detected, the
device will send an alarm signal.
Time Synchronization
Clock synchronization makes comparison of events
and disturbance data among all IEDs in the system
possible.
In the IED, the internal time can be synchronized from
the following sources:
•
SNTP
•
IRIG-B
Authority management ATMNG
All access to device requires authorization. Setting up
users and managing authority levels is realized via the
HMI. There are 3 levels of operation authority: system
management, equipment maintenance and settings
modification.
