Beyond AMI
 Demand Management
 Most utilities have demand
management accounts that
require real time data to take
full advantage of special rates
 AMI infrastructure not
always practical for every
location
 Customer access to data is
critical

HawkEye Elevated Metering System
 HawkEye was designed
for the Aboitiz group of
utilities in the
Philippines
 Revenue protection is
critical
 Meters mounted in
“billboards” atop poles
 Meter reading done with
high resolution camera
Confidential
HawkEye
 HawkEye is
designed to provide
high security
elevated metering in
a compact, easy to
install system.
Confidential
HawkEye
 Modular compact meter
design
 Each meter contains two
100A relays for remote
connect/disconnect
 Remote display for
centralized customer
access
 Tamper detection
Confidential
HawkEye
 Meters utilize optical
communication with
RadioGate for increased
security and reliability
 RadioGates capable of
mesh communication
between enclosures
 Prepay metering capable
using STS protocol
Confidential
Cogeneration Metering
 Metering solution for
installations that are
powered from
cogeneration sources or
non-utility owned
sources
 Desired a single meter
solution
Confidential
Cogeneration Metering
 Vision meter customized to detect alternate
supply voltage
 When voltage detected on alternate supply,
meter transitions power from kWH delivered
register to kWH delivered power even though
current flows in same direction
Confidential
Expanded Drive By AMR
 Vision was approached
by several utilities
seeking to expand their
drive by SCM message
capabilities
 Time of Use not
compatible with existing
SCM technology
Confidential
Expanded AMR
 Current revenue meters
only capable of up to 3
SCM ID’s
 SCM only configure for
kWH registers, not TOU
 Utilities desired up to 5
SCM ID’s with fully
customizable payloads
Confidential
Expanded AMR
 Vision Meters now support 5 fully customizable
SCM’s including:

Magnetic Tampering
 Magnetic Tampering

All solid state meters
currently offered in the US
are susceptible to
magnetic tampering
Singlephase meters
 More importantly,
Polyphase meters!

Confidential
Magnetic Tampering
 Solid State meters are vulnerable to high strength
magnetic fields in two manners


Power supply
Current Sensing
 AMI meters equipped with remote disconnects can
also be opened/closed with magnets
 So, what kind of magnet is needed?
Confidential
Magnetic Tampering
 Magnetic fields that
exceed as little as 5,000
gauss can affect the
accuracy of solid state
meters
 As field strength
increase, meter accuracy
goes down rapidly
Confidential
Magnetic Tampering
 Rare earth magnets are

readily available on the
internet
The magnet shown here
produces a 13,000 gauss
field
2” x 2” x 1”
Available for under $40
Will self adhere to meter
cover
Confidential
Magnetic Tampering
 Accuracy affected by
anywhere from 25%-75%
on every meter tested
 Some meters actually
shut down due to the
magnetic field
Confidential
Magnetic Tampering
 So what can be done?
 Meters can contain magnetic tamper detection


Utility may be alerted but revenue still lost
Meters can move CT’s and power supply closer to center of
meter
Not effective against strong magnetic fields
 Not possible with AMI meters that have remote disconnects


Meters can use shielded CT’s and power supplies
Best solution, makes meter immunes to magnetic tampering
 Adds nominal cost and weight to meter
