Applications
MPR-3 series analyzers are 3 phase network analyzers. They are microprocessor-based
devices designed to measure all parameters of an electrical network, calculate consumption
and display them on the LCD screen.
Thanks to the RTC clock chip and ash memory on the device, the operations performed
by the operator such as interruption records, time and setting changes, reset operations are
recorded in real time. These records can be remotely read and monitored with Modbus RTU
protocol over RS-485 communication line.
The current connection is made by connecting to a 1A or 5A secondary current transformer,
depending on the selected model, or to a current transformer with mV voltage output with
RJ-45 connector.
The connection control function should be used against the problem of exposed live ends
that may occur due to possible rupture in the terminals.

Button Functions
4 buttons are used on the front panel. All the buttons used here can be used for additional
functions other than their main functions which can be accessed by pushing for 3 seconds.
Button function descriptions are as below:
•BACK button (24) : It has 3 basic functions:
• It is used to return to the upper menu from any menu.
• While on measuring screen: As seen from the notation on the button (V I F), Current,
Voltage, Frequency and Time counter is used to monitor values and switch between the
related screens.
• It provides access to event screen when pressed for 3 seconds (Event).
•DOWN button (26) : It has 3 basic functions:
• While on measuring screen: As seen from the notation on the button (P PF), it is used
for monitoring the Total, Active, Reactive, Apparent Power, Cosφ and the values measured
related with the Power Factor.
• While in the menu screens, it is used to move up in the menu and to increase the adjusted
values.
• While on measuring screen: When pressed for 3 seconds, the device swicthes into the
connection test mode (Test).
•UP button (25) : It has 2 basic functions:
• While on measuring screen: As seen from the notation on the button (E H), it is
used for monitoring Harmonic measurements on the Voltage-Current screen and Energy
measurements on the Power screen.
• While in the menu screen, it is used for moving downyards in a menu and decreasing the
adjusted values.
•SET button (27) : It has 3 basic functions:
• While on measuring screen: As seen from the notation on the button (Max / Min), it is
used for monitoring the Maximum, Minimum, Demand and Max Demand measurements of
the related screen while you are on the Voltage-Current and Power screens.
• It provides access to setting screens when pressed for 3 seconds. When the PIN is active,
PIN is requested to enter the Menu and the menu is accessed only if the correct PIN value
is entered.
• It is used to access the setting to be changed and save the changes, if it is required to
make changes on the settings by using the menu steps. It is enough to push the button for
a little while for this process.
CONNECTION TYPES
As there are shunts at the current measurement inputs of the device, it is mandatory to use a
current transformer for the connections of current inputs. If the device will be used with other
analyzers on the same panel, it is recommended that the device is located at the last point on
the current measurement line.
The device has 5 di󰀨erent connection types. These connection types are described in the
following schemes:

11
3P4W (Three-Phase Four-Wire) Connection
As it is seen below, four voltage and three current connections including the neutral line are
established in this connection type.
3P3W (Three-Phase Three-Wire) Connection
As it is seen below, three voltage and three current connections are established in this
connection type.
ARON Connection
Three voltage and two current connections are established in this connection type. As it is seen
in the following gure, the current connections are established with the 1st and 3rd phases.

12
3P4W BLN (Three-Phase Four-Wire Balanced) Connection
Four voltages and one current connection are established in this connection type. The device
displays the value measured at the current input connected to the rst phase on its screen for
other phases in the same value.

3P4W BLN (Three-Phase Three-Wire Balanced) Connection
Three voltage and one current connections are established in this connection type. As it is seen
below, the device displays the value measured at the current input connected to the rst phase
on its screen for other phases in the same value.
Connection Control
After the connections of the device are completed, you can check the connection you
established by using the test functionality.
The device switches into the connection test mode if the BACK button is pushed for 3 seconds.
-At least 20% of the nominal voltage must be applied to the voltage measurement inputs.
-At least 10% of the nominal current must be applied to the current measurement inputs.
-The angle di󰀨erence between the current and voltage inputs should be less than 30 degrees
(Cos φ value should be between 0.87 inductive and 0.87 capacitive.)

13
In this mode, the device can control the connections and if there is any fault through the current
ow directions, it can correct such faults by software or leave it to be handled manually by the
operator.
If there is any connection fault between voltage inputs, this fault can only be corrected by
changing the cable connection points.
If you experience the fault number 12, please make sure that all connections are established
and the aforementioned minimum current and voltage values are applied on the device.
The possible connection faults as a result of the connection test process and the codes
displayed on the device screen for these faults are indicated in the following table:
Test Fault Code Description
0All connections are correct
1Reverse Phase-1 current direction
2Reverse Phase-2 current direction
3Reverse Phase-3 current direction
4Reverse Voltage connection of Phase-1 and Phase-2
5Reverse Voltage connection of Phase-1 and Phase-3
6Reverse Voltage connection of Phase-2 and Phase-3
7The Phase sequence of voltage connection as L1, L2, L3 will be changed as L3, L1, L2.
8The Phase sequence of voltage connection as L3, L2, L1 will be changed as L3, L1, L2.
9CT-1, CT-2 will be changed.
10 CT-1, CT-3 will be changed.
11 CT-2, CT-3 will be changed.
12 Minimum test conditions of 20% of the rated current and voltage are provided.
Communication Line Termination Resistance
On RS485 lines, when the communication distance exceeds 10 meters and there are more than
one device on the line, a 120 Ω line termination resistor should be installed between the A and B
ends of the device that is the farthest from the communication terminal.
