Simple integration into any architecture
iRTUe#Q are the power quality devices of the iRTUe family, the I/O auxiliary equipment for iRTU /iGW or third party controllers and master devices.
The iRTUeQ is a high performance (IEC 61850 GOOSE & Modbus ready) power quality analyzer for continuous measurements of electrical power and power quality parameters in three-phase AC grids. It helps to reduce costs and complexity thanks to its easy set-up and versatile functions. The device is designed in a simple and flexible way, combining multiple communication options and I/O configurations to fulfill any application requirements and replace several devices to save money and space on the DIN rail.
iRTUe#Q power quality analyzers can be connected to traditional sensors (CT-current transformers and PT-power transformers) or new sensors, with integrated V/I measurement and low voltage output (IEC 60044–7/8), in order to measure, detect and store the data of the received waveforms.
Its 3 voltage and 3 current inputs for high-accuracy, three-phase power quality measurements in compliance with IEC 60044–8 as well as 24 digital inputs (optional) allow to collect data from other devices in the substation and expand the acquisition and command capabilities of any master device.
It can directly communicate with iRTU & iGW units and other iRTUe I/O modules with its integrated ports (serial, 2x Ethernet), both using Modbus RTU or IEC 6180 GOOSE messaging with high-precision time synchronization through NTP or IEEE 1588 (PTP).

iRTUE#Q in Substation Networks
iRTUe#Q are equipped with a serial (EXP422 port) or double Ethernet port (ST or SC) to connect to iRTU/iGW units and other iRTUe I/O modules, both using Modbus RTU or IEC 6180 GOOSE messaging. iGW/iRTUs allow to integrate and communicate with all kinds of devices, providing protocol conversion between any substation protocol, including IEC 61850 and up to (48) digital inputs and (24) outputs as well as (16) analog inputs. Paired with an iRTUeQ, they can act as advanced, all-in-one controller/ RTU, providing data logging, fault recording, load curve conversions, COMTRADE file generation and time synchronization (via PTP).
IEC 61850 based systems are based on software configurations rather than hardwired signal paths, making them more cost-effective, easily extendable and on-demand reconfigurable. As GOOSE messages are sent IED-to-IED, they avoid additional delays from intermediary equipment and blocking signals can be sent faster than in traditional schemes. Furthermore, signals can be sent to all IEDs at once, minimizing the operating time in any kind of network.
With the ultra fast processing time (P2/P3) of iRTUe units you can take full advantage of IEC 61850. Integrate high speed analog and digital power quality measures, as well as relays and other devices through powerful and direct communications.
iRTUe#Q Communication Network Architecture
The units can carry one serial RS422 port to connect to iRTU & iGW devices via ModbusRTU or two 100 BASE FX/ 100 BASE TX Ethernet ports with ST or SC connectors to use advanced IEC 61850 GOOSE communications.
IEC 61850 GOOSE
GOOSE communication works with enhanced retransmission mechanisms on a publisher/subscriber basis, allowing P2P communication between iRTUe and IEDs with a processing time under 3ms (performance class P2).
IEC 61850 GOOSE also features strong VLAN and priority tagging functionalities via IEEE 802.1Q to send messages efficiently across complex physical networks. Combined with a substation-wide Ethernet LAN, it enables flexible and sophisticated logic schemes for substation protection and automation, such as interlocking and load shedding.
The device can act as over current fault detector (max: 100A) , creating customized alarms triggered by any user-defined conditions and thresholds, (e.g. sag/swell) easily configured with the free iConf tool.
iRTUe addresses, in both Modbus and GOOSE, can be quickly set up using the side microswitches.
Paired with a substation automation controller/ RTU such as an iGW or iRTU, iRTUeQ models allow to process, store and convert thousands of time-stamped events, data points, waveforms and load profiles.
Further, the measurements can be converted into user-defined COMTRADE files (sampling rate 1,25ms), which can be accessed or transferred via ftp and web services.
Functioning as a fault recorder, the device can easily store 2048 SOE records, which can turn into many more using the internal SD card.
iRTUe addresses, in both Modbus and GOOSE, can be easily configured using the side microswitches. For GOOSE, the default multicast group is set to zero (modifiable with iConf).
Power Quality Measurements
As power quality I/O extensions of the iRTUe family, iRTUe#Q provide high-speed collection and transmission of a large number of three-phase power measurements and parameters (frequencies, currents, phases etc.).
The Q1 model connects to traditional sensors such as current and power transformers through 3 voltage and 3 current inputs: MVSTBR 5.08 6 pins (for current) and 4 pins (for voltage) with 0.3% accuracy.
Q2 units connect to new sensors with integrated V/I measurements and low voltage outputs (IEC 60044–7/8, combined inputs via 3 RJ45 connectors).
Each input can be defined as input or as a counter and have an individually configured debounce filter. One iRTUe unit can provide up to 48 isolated digital inputs with a 2.5kVrms isolation and a 1 ms timestamp accuracy. The units come in standard input voltages of 24, 48, 125 or 220 Vdc.
