What is Electricity Theft?

• Obtaining electricity without Utility approval constitutes electricity theft and is therefore illegal. Among the methods commonly used to illegally abstract electricity are:– direct connections to power lines using ‘throw-up’

lines and wires – meter tampering to cause the meter to under-register

the amount of electricity actually consumed – meter by-pass to cause all or some of the electricity

consumed to go undetected by the meter

• Identify tampering by measuring both delivered and received energy in separate register

• Detecting inverted meters • Frequent unplanned outages • Reverse energy flow• Illegal connections• Use of connect and disconnect switches• Use of prepay meters

AMI


Residential AMI

• Residential AMI system – Single electronic meters with remote disconnect/reconnect

switches– Up to 24 electronic meters with remote disconnect/reconnect

switches to be installed inside a single meter cabinet– Prepaid meter

• Facilitate remote monitoring of customer meters and quick detection of attempts at tampering

• View usage and consumption patterns on a display unit placed inside their homes

• Utilize “Transformer Meter” to identify possible energy theft


Feeder by Feeder Analysis

• Examining the losses on individual power distribution circuits, beginning with the feeders with high percentages of losses

• Installation of “Feeder Meters” and “Transformer Meter” to measure total consumption on transformer circuits, and inspection of individual meters on the feeder

SMB and Large Account Audits

• Routine audits of large commercial and industrial customers – to detect and prevent diversion of electricity

• On going audits

• Use of AMI


Theft-Resistant Distribution Network

• Replace lines with insulated conductors

• Audit of zero-consumption customers• Removal of inactive account service equipment• Inspection of residential meters• Meter sealing• Prepaid meters• Arrest of perpetrators • Community relations and public education

Theft-Resistant Process


• One size does not fit all• Solution should be considered based on the

distribution topology, geographic/demographicsand cost/benefit

• Some solution may cost more but could provide greater benefits

• Can’t replace your “Loss Investigation” group• Utilize “Smart Grid/AMI” data to your advantage
