The Iskra MT174 electronic three phase meters are designed for measurement and registration of active, reactive and apparent energy and demand in three phase four wire networks. They can be connected directly to the network. The metering and technical properties of the meters comply with the EN 50470-1 and -3 European standards for active energy meters, classes A and B, as well as with the IEC 620553-21 and IEC 62052-11 international standards for electronic meters of active energy for classes 1 and 2, and optionally with the IEC 62053-23 international standard for electronic meters of reactive energy for classes 2 and 3.

The Iskra MT174 meters are designed for mechanical environment M!, electromagnetic environment E2 and climatic environment -40 degrees … +60 degrees, relative humidity 95% non condensing, closed location. These meters can be installed in any position and available in either CT operated or DC applications.

The EMGSM1 is designed specifically for the collection of micro-generation metering data, EMGSM1 provides remote collection of meter readings especially generation metering of wind, solar and any other renewable energy installations. The meter is of modular construction and allows a range of communication modules to be fitted to allow for future developments in remote metering.

The meter is a fully MID approved device and can provide functionality over and above that required for generation metering making it suitable for many other applications. Additional functionality includes Time-of-Use Rate Switching, Power Quality Recording, Active (kWh) and Reactive (kvarh) energy measurement across both import and export.

To read these smart meters remotely you will need Meter Online unless you have your own AMR system.
