iGW: Smart Meter Gateway

The Smart Metering data collection solution

Product highlights

  • Availability of the most popular metering protocols: IEC60870-5-102, Modbus and DLMS
  • Ability to collect information from the plant (up to 24 meters) through IEC60870-5-102, DLMS or Modbus
  • Information collected from the plant is processed by iGW, allowing any kind of user mathematical/logical operation in order to create new data that will be sent to the control center
  • Data is sent to Control Center via any kind of communication network available in the plant (GPRS, VSAT, analog radio, Ethernet, ..) using standard communication protocols (IEC60870-5-101/104, Modbus, DNP3.0)
  • iGrid T&D solutions have been tested with most of the leading manufacturers of smart meters (Landis&Gyr, Itron and Circutor).

Technical features

iGW Series provides a Smart Metering data collection solution that allows utilities to accurately collect metering data from substation and generation plants, such as:

  • Tampering detection
  • Billing data
  • Generation regulation
  • Consumption and generation trends
  • Loss calculation
  • Power quality: total harmonic distortion (THD) and power factor (PF)

 

iGW Smart Metering series uses the most popular metering protocols: IEC60870-5-102, DLMS and Modbus. iGW devices collect real-time information from all the meters in the facility, with reads taken at really short intervals (every 2-4 seconds). Metering data can then be transferred to control center/s via any kind of communication network available in the plant (GPRS, VSAT, analog radio, Ethernet, etc.) using standard communication protocols (IEC60870-5-101/104, Modbus, DNP3.0).

iGW series products have been tested with most of the leading manufacturers of smart meters (Landis&Gyr, Itron and Circutor).
