Electricity Theft is a very common problem incountries like India, where population is very highand the users of electricity are ultimately tremendous

In India the losses are currently 29 percent of thetotal generation which equals 45,000 crores in the

year 2009-10.

Electricity theft can be detected by AMR via powerline communication

LOSSES IN POWER SYSTEMTechnical Losses : It includes resistive losses in the

primary feeders, distribution transformer losses

resistive losses in service drops, and losses in kWhmetering

Non-Technical Losses : It occurs as a result of theft,metering inaccuracies and unmetered energy. Theft ofpower is energy delivered to customers that is notmeasured by the energy meter for the customer

AUTOMATIC METER

READING

AMR is a technique to facilitate remote readings of

energy consumption through digital communication.

In most cases, the meter that is used in an AMR systemis the same ordinary meter used for manual reading

but the difference with conventional energy meter is

the addition of some device to generate pulses relating

to the amount of consumption monitored, or

generates an electronic, digital code that translates to

the actual reading on the meter dials.

POWER LINE

COMMUNICATIONPower line communications take place over the samelines that deliver electricity. This technique involves

injecting a high frequency AC carrier onto the powerline and modulating this carrier with data originatingfrom the remote meter or central station. Power linecommunications has many new service possibilities on

the data transferring via power lines without use ofextra cables.

MODELING OF DETECTION

SYSTEM


12/20

SMART METERS

Smart meter is usually an electrical meter thatrecords consumption of electric energy in intervalsand communicates that information back to theutility for monitoring and billing purposes.

Time-based pricing

Net metering

Loss of power notification

Remote turn on / turn off operations Energy prepayment

Power quality monitoring

Tamper and energy theft detection

THEFT DETECTION

FEATURES OF SMART

METERSMeter cover open alarm immediately reports on the

opening of the smart meter.

Reverse current alarm detects rewiring of the meter

causing the current to flow in the reverse direction (may

cause the meter to count back if not taken care of).

Phase unbalanced alarm detects tampering with the

electricity wires.

PROVISION FOR

ELECTRICITY THEFT

Focus on Revenue Realization rather than Criminal

Proceedings

Theft Punishable with Imprisonment

Punishment Provision for Abetment of Theft

Penalties linked to the Connected load and Quantum

of Energy and Financial Gain involved in Theft

Special Courts


17/20

ADVANTAGES OF AMRAccurate meter reading, no more estimates

Improved billing

Improved security and tamper detection for

equipment

Power quality monitoring

More accurate


18/20

DISADVANTAGES OF AMR

Loss of privacy - details of use reveal information

about user activities

Reduced reliability

Increased security risks from network or remote access

Meter readers losing their jobs
