DIGIPROT-EP
|
|
| DIGITAL DISTURBANCE RECORDER |
| |
| The digital disturbance recorder DIGIPROT-EP
is part of device family named EuroProt. This short description contains
special data of this type. General and common features of EuroProt family
can be found in the EuroProt system information sheet. Accordingly it is
proposed to study both this short description and system information sheet
too, in order to understand the device entirely. |

|
| |
| Application field |
| |
| The digital disturbance recorder of type DIGIPROT
-EP has been developed for recording and storing analog signals of voltages
and currents and digital signals.The DIGIPROT -EP disturbance recorder is
suitable to record events of protections, automatic equipment's, CB's, e.t.c.
when short circuit or other abnormality occurs on a high voltage network,
included the pre- and post-time periods as well. |
| |
| Main features |
| |
- Each analogue input board (PCB =printed circuit board) contains 3
identical transformers (CTs or VTs)
- Maximum number of analogue PCB's is 5 pcs, i.e. maximum 15 analogue
input channels can be recorded in each device
- Each digital input PCB contains 8 optical coupled inputs
- The number of digital PCB's can vary 2 to 8. Since the data storage
is 16 bit wide the number of digital input boards must be an even number.
i.e. 16, 32, 48 or 64 digital input channels can be recorded in each
device
- Since the size of the rack or case in which a disturbance recorder
is built in and theterminal number of a recorder is limited,16 PCB places
are the maximum. Since an analogue board takes tv.o places, the maximum
channel number is as follows: 2/3 x analogue channel number + 1/8 x
digital channel number + 3 ~ 16 (+ 2 means supply PCB, 1 means CPU)
- Sampling time is 0.5 ms for analogue signals and 1 ms for digital
inputs
- Analogue signal resolution is 12 bit NO conversion but 15 bit signal
range due to an automatic measuring range
changeover
- Memory capacity is 1, 2 or 4 MB SRAM card with battery backup
- Recording time is 25 to 250 s depending on the number of input channels
and the memory capacity
- Record overwrite at full memory capacity but time-date inquiring possibility
of overwritten record
- Consumer-friend modern digital parametering (setting) method for time
period data of maximum record, pre-record and post-record after edge
start, for channel titles, for starting setting both entering edge and
negative-going edge of each digital input, and over/under-current/voltage
of each analogue channel, for primary measuring transformer ratios
- Independent event sequence recorder for 300 events with real date
and time
- 4 output alarm relays of warning signals for start, for memory 75%
full, for record overwrite on memory quite full, for inner failure monitoring
- RS 232 or optical fibre cable for external serial communication
- WINDOWS based software for high performance evaluation
- WINDOWS based 24 hour saving system for automatic data store of several
DIGIPROT disturbance recorders and protection relays with remote workstation
capability
- Fast checking possibility of the setting data
- Password protection against unauthorized setting action
- Fast inquiring possibility of actual operation data (e.g. channel
state)
- Real time clock handling synchronizable by external PC or by local
area radio transmitter
- Immediately appearing "messages" on recording
Setting (parametering) and checking of digital disturbance recorder,
inquiring of the recording data, events and signals, and recorder setting
values, setting of software matrix, and handling of automatic signals
(messages) is possible with a built-in LCD of 2x16 characters and six
push-buttons on interactive mode by the aid of a menu system or with an
external PC. PROTECTA Co.Ltd. gives a handling program together with the
DIGIPROT disturbance recorder to make handling functions possible by an
external PC.

The digital disturbance recorder type DIGIPROT-EP
is a member of the device family EuroProt. It has two different designs.
The one is a device for rack mounting to a 19" standard cabinet frame,
the other is a flash mounting or raising mounting device to a panel. Its
size depends, of course, on the design chosen. The disturbance recorder
is controlled by microprocessors and equipped with module system of plugged
in PCB's, set up of IC's. DlGIPROT -EP disturbance recorders are housed
in two forms. Sizes are as indicated in the following table.
