To optimize $$$, the firmware is written very tightly coupled to the hardware

To optimize $$$, the hardware is as minimal as it can be

To add many new features requires hardware changes and support from many utilities

This requires re-writing the firmware for the new hardware

Metering applications might differ significantly from location/customer

types of calculations

access requirements (data, security, interface)

What would be required to have a ‘one size fits all’ meter?

Maximal flexibility of:

Hardware

Firmware

Configuration capability

Optimized for Flexibility, not $$$

Not a Commodity item (higher priced)

Applications are typically where the price of the meter is insignificant relative to the monthly ‘solution’

High end electronic meter technologies

• Meter to periodically performs a self test (on site diagnostics) to determine if it is operating correctly

• The meter self test to be performed automatically under the following situations:

after any power restoration following an outage

at midnight or every 24 hours from initial power up.

immediately after a communications session to insure data transmission

• Specific tests peformed:

verification of configuration data

confirmation of the crystal oscillator accuracy

detection of low battery voltage (for TOU configurations)

verification of normal microprocessor functions

detection of unexpected microprocessor resets

Meter Manufacturers Face Issues with Modems…..

• Integrating modem communications with Meters is not trivial

• Which communication systems to support ? How much data needs to be typically read ? How often ?

• Are there commercially available radios/modems? Will they meet Meter temperature standards? How durable is the modem?

• What are trade-offs between First Cost and on-going communications / maintenance costs? Will a Utility look at Life Cycle Costs or First Cost only? What timeframes are considered? 2, 5, 10, 15 years?

• If we build an amazing new widget, what can read it ? Are there Master Stations or Communication Servers available ? Will it work with MV90 ? Will it support the functionality the utility wants ?

Metering Communications Is Becoming a Major Issue

• Meter Data needs & Reading Frequencies are increasing, particularly for C&I

Remote AMR communications replacing monthly meter reads

Daily reads of load profile for data posting to Internet

PQ Events / Outage call-ins

Interest in TOU and Real-time pricing

• Selecting a suitable metering communications technology is thus becoming a major issue Ongoing operating costs are a key concern And functionality is a key issue
