ROGOWSKI SENSOR

The Rogowski sensor is a ring-shaped device designed for measuring AC, impulsive or complex waveforms.

For its correct use:

- wrap the ring on the conductor so that the arrow symbol shown in the ring is oriented in the same direction as the

conductor current

- make sure that the connections are made correctly

- for a more precise measurement, the conductor cable must be placed in a central position with respect to the ring

- for a correct measurement, calibrate the Rogowski sensor by writing the calibration coefcient in the

corresponding Modbus register (see the user manual).

Example: if the sensor is supplied with a characteristic of 90 mV / 1000 A, on the calibration register

corresponding to the phase in which the Rogowski sensor is applied, the value to be set is: 1000 / (90 · 10).

NOTE ON ACCURACY: The product has a nominal accuracy of 0.5%. The total accuracy is the sum between the

accuracy of the device and the accuracy of the Rogowski sensor connected to it.

ELECTRICAL CONNECTIONS

NOT CONNECTED

The power supply is connected to terminals 40 and

41.

The supply voltage must be: 90 ÷ 264 Vac, 50 ÷ 60 Hz

It is advisable to insert a delayed 1 A fuse

GND

There is no isolation between RS485 and analogue

output.

POWER SUPPLY

RS485

ANALOGUE OUTPUT

The device provides a voltage output (0 ÷ 10 Vdc) or

programmable active or passive current (0 ÷ 20 mA).

For the electrical connections, screened cables are

recommended.

There is no isolation between RS485 and

retransmitted output.

It is necessary to program the outputs to use them

correctly.

ELECTRICAL CONNECTIONS

The installation of this appliance must only be carried out by qualied personnel.

Check that the device plate data (measurement voltage, auxiliary power supply voltage, measurement current, frequency)

match the actual data of the network to which the instrument is connected. In the wiring, strictly observe the insertion

diagram; inaccuracy in the connections inevitably causes false measurements or damage to the instrument.

Once the instrument is connected, complete the installation with the device conguration.

Grounding of the TA sensors is possible with negative cable connection.

Current measurement is only possible using current transformers.

It is advisable to insert a delayed 1 A fuse as shown in the diagrams below.

DAISY-CHAIN ETHERNET CONNECTION

CAUTION

IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES

Using the daisy-chain connection it is not necessary to use switches to connect the devices.

The following examples show the correct connections.

There must be no loops in the Ethernet cabling, otherwise the communication will not work.

The modules and switches must be connected eliminating any loops.

The following examples show the incorrect connections.

The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of

the device ON, in the event of a power failure. If a device turns off, the chain is not interrupted and the

devices downstream of the switched-off one will still be accessible. This function has a limited duration:

the connection remains active for a few days, typically 4. The fault-bypass function requires that the sum

of the lengths of the two cables connected to the switched off module is less than 100m.
