DPR-400 User Manual Rev_01 Firmware V-1.0
DPR-400 is a state of the art, color screen,
directional network analyzer and protection relay in
144x144mm standard panel dimensions. Thanks to
its low depth, it saves space in the panel. The device
combines high precision, ease of use and versatility
with a reliable and cost-effective design.
The DPR-400 features dual current measurement
circuits, making it a class 0.5% accuracy analyzer,
and a protection relay capable of measuring 50xIn.
The DPR-400 offers various protection curves to
provide precise protection. Multiple protection curves
can be activated simultaneously.
The DPR-400 displays multiple measurements on its
4.3”screen. The large display offers ease of use and
provides abundant information.
The device can connect to various Scada systems
easily via USB, isolated RS-485 and Ethernet ports
for remote monitoring.
Modbus and IEC60870-5-103 protocols are
supported through RS-485 port.
Modbus TCP/IP and IEC61850 protocols are
supported over the Ethernet port.
Parameter configuration is done using the buttons on
the front panel or with the free PC software. The
program connects via USB, RS-485 or optionally
over the Internet. Additionally, firmware updates are
performed through the USB port.
Two of the relay outputs of the device have
connection monitoring capability. These outputs
continually check the integrity of the load circuit, and
raise an alarm if the circuit opens.
DPR-400 stores up to 7 oscillographic records in
COMTRADE format in its 1MB internal memory.
The device meets the security, EMC, vibration, and
environmental standards for industrial products.

Although the unit is protected against electromagnetic disturbance, excessive disturbance can affect the
operation, measurement precision and data communication quality.
▪ALWAYS remove plug connectors when inserting wires with a screwdriver.
▪Fuses must be connected to the power supply and phase voltage inputs, in
close proximity to the unit.
▪Fuses must be of fast type with a maximum rating of 6A.
▪Use cables of appropriate temperature range.
▪Use adequate cable section, at least 0.75mm2 (AWG18).
▪Follow national rules for electrical installation.
▪Current transformers must have 1A or 5A output.
▪For current transformer inputs, use at least 1.5mm2section (AWG15) cable.
▪The current transformer cable length should not exceed 1.5 meters. If a
longer cable is used, increase the cable section proportionally.
2.3. ELECTRICAL INSTALLATION
Do not install the unit close to high electromagnetic
noise emitting devices like contactors, high current
busbars, switch mode power supplies, etc.
For the correct storage of event records, adjust the
real time clock through the programming menu.

SELECTING THE CT RATING AND CABLE SECTION:
The load on a CT must be kept minimum in order to
minimize phase shift effect of the current transformer.
Phase shift in a CT will cause erroneous power and
power factor readings, although the amp readings are
correct.
It is advised CT rating to be selected following this table
for the best measurement accuracy.
SELECTING THE CT ACCURACY CLASS:
The CT accuracy class should be selected in accordance
with the required measurement precision. The accuracy
class of the controller is 0.5%. Thus 0.5% class CTs are
advised for the best result.
CONNECTING THE CTs:
Be sure to connect each CT to the related phase input with the correct polarity. Mixing CTs between
phases will cause faulty power and power factor readings.
Many combinations of incorrect CT connections are possible, so check both the order of the CTs and
their polarity. Reactive power measurement is affected by incorrect CT connections in a similar was as
active power measurement.
