ION meters - Support for IEC61850-9-2LE

[jorge_afonso_em]

Hi Community

Can someone please inform if the implementation of IEC 61850-9-2LE (Process function) is supported by some ION meter. If yes please inform which type of meter to consider.

Thank you very much

@Daniel_Brandao hey Daniel - do you have information on the specifics of 9-2LE and if we support this with any of our meters?

IEC 61850, in very general terms, is separated into 2 parts - the Station bus and the Process bus.   The Station bus receives data from the Process bus and is used to exchange data from the substation to supervisory systems,  The performance of the Station bus is non-deterministic.   The Process bus is a high-speed, deterministic bus that provides the connection between digital sensors and merging units where sensor data is collected and shared with the Station bus.   

The IEC 61850-9-2 LE deals with the Process bus and defines the connection between sensors with digital outputs and merging units, or units that collect signals from digital sensors.   This is typically a very high-speed fiber optic network with deterministic response.   

ION meters are deployed in IEC 61850 systems at the Station bus level.  They accept input from current and voltage sensors with analog outputs.   ION meters do not support sensors with digital outputs and cannot be deployed on or receive input from the IEC 61850 Process bus.  Therefore, there are no ION meters that support IEC 61850-9-2 LE.

Any upgrades on this subject? any compatible meters?

I cannot speak for all meters, but for ION meters still the same.
