Meter Selection
Meter Selection
(OP)
I am helping a customer select a metering solution to replace their existing metering. This is in the midwest on Alliant Energy's system. The customer has an existing Allen Bradley PLC/Automation system and is wanting a meter where they can pull in this data and in particular provide some visibility into the power factor for their facility. The old meters for the 5 services only have kW*hr available. Metering selection(s) are usually driven by utility requirements is my current understanding, which I'm in the process of digging through. In terms of grabbing data from revenue grade meters that can be utilized within a facility, can anyone comment on a meter and communication solution that might work to integrate with existing Allen Bradley automation platform?
This customer is also looking for some power factor correction and this is what is driving the need for visibility into power factor.
Thanks in advance.

I have also recently done a few system upgrades with the SEL 735, and brought metering data to Allen Bradley PLC's via Modbus TCPIP thru a ProSoft card, not the cheapest route but the customers were happy with the results.
But, as pointed out above, if your are trying to replace utility metering with something else you may be in for a fight. And if you want to add supplemental metering to an existing utility service you likely can't share PT's and CT's.
Maybe some more details on your system could get you some better answers?

Traditionally, data could be provided using a meter with KYZ pulse outputs. Now it would be more likely to be through a Zigbee radio link. Sharing of VTs (separately fused) has been approved. Sharing of CTs; nope.
No fighting involved at my local utility, just pay all the costs involved. Meters plus spare if non-stock, labor, vehicle charges, overhead, etc.)
