DPR-350 User Manual Ver_01 Firmware V-1.0
DPR-350 is a state of the art network analyzer and
protection relay in 96x96 standard panel dimensions.
Thanks to its low depth, it provides space economy.
The DPR-350 features dual current measurement
circuits. It is both a precise analyzer and a protection
relay. Protection curves can be selected among IEC,
ANSI, UK and US standards. Multiple protection curves
can be activated simultaneously.
Multiple measurements can be viewed on the 128x64
pixel graphic display of the device.
The unit records every electrical parameter to its built-in
1MB (16MB optional) memory at the desired sampling
rate. The records can be read via Modbus.
Through its RS-485 port, the unit can connect to various
Scada systems and can be remotely monitored.
Parameter configuration is done via USB port.
The unit offers 4 digital inputs, 2 relay outputs, and 3
analog outputs as standard. Analog outputs can be used
to receive desired measurements in the form of 4-20mA
signals, or to drive a visual fault mechanism.

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.
