Power Quality meters

Do we have a future plain to implement sampled value(with 61850-9.2 process bus) measuring inputs to some of revenue ION meters like ION 8800, ION7650, ION8650?

On the technical side, we have looked at the process bus before.  One of the challenges is the fact that standard sampling rates supported are significantly lower than the sampling rates used on these meters.  Using the sampling rates outlined in the standard would likely result in degraded accuracy and limitations on PQ functions for these meters.

On the marketing side, I would defer to someone in offer creation for a formal answer.  To my knowledge, though, there is no immediate plan to implement it on these meters.

If you have knowledge of a customer application that would benefit from this feature, I would be very interested to hear more!

This issue reminds me of what the utility told me that our competitor L&G had informed them that they have just developed the revenue meter that work on process bus accurately. Then I commented that our sampling rate is higher than the merging unit do they agree with me and said "oh yes you are right the high accuracy on low resolution signal".
