INTRODUCTION

Many developing countries confront widespread theft of electricity from government owned power utilities.

In India electricity theft leads to annual losses estimated at US$4.5 billion, about 1.5 percent of GDP.

Who are the losers??Honest consumers, poor people, and those without connections, who bear the burden of high tariffs, system inefficiencies, and inadequate and unreliable power supply.

INDIA’S GENERATION CAPACITY

The Installed Capacity of the country as on 31st December, 2011 was 1,86, 655 MW as depicted

India has been facing growing shortages over the past five years. During the year 2007-08peak deficit:8,000 MW (16.5%)average energy shortage:73 Billion kWh (10%). During the year 2008-09peak deficit 13,000 MW (12%)average energy shortage: 86 Billion kWh (11%). During the year 2009-10peak deficit:5,157 MW (12.7%)average energy shortage:84 Billion kWh (10.1%).

ELECTRICITY THEFT

WHAT IS ELECTRICITY THEFT….???

It is the use of electrical power without a contract with a supplier with total or partial bypassing metering system

OR

Interfering this system in the way to adulterate its measurements.

10

Absence of accountability.

Inadequate and ineffective enforcement of law.

Political protection to employees and influential customers.

Customer attitude: “Immoral to steal from neighbor but legitimate to steal from state’’.

MAJOR CAUSES OF ELECTRICITY THEFT

11

WHERE DOES ELECTRICITY THEFT OCCUR MOST COMMONLY

12

Meters: • Tampering with meters and seals • By-passing the meters • Damaging or removing meters

Wires/ Cables:• Illegal tapping to bare wires or underground

cables

Transformers:• Illegal terminal taps of overhead lines on the

low side of the transformer

Billing irregularities made by meter readers.

Unpaid bills by individuals, government institutions and “untouchable” VIPs.

ELECTRICITY THEFT METHODS

13

FEW OTHER WAYS FOR POWER THEFT

�Use of single phase supply from three phase supply.

Disconnected neutral from both the ends.

Used earth/separate neutral for return circuit.

Connecting phase voltage to neutral of used single phase supply. Potential difference w.r.t. neutral of used single phase supply is zero. Hence power product of voltage and current, will be zero.

Isolating neutral from both ends.

14

THEFT OCCURS WHEN:

An illegal consumer(not a registered customer) steals directly from the distribution lines or from another legal customer. A legal customer(registered customer) steals either bypassing the meter (connecting around the meter to a live cable on the company side of the meter) or tampering with the meter to make it read less or no consumption.

There is a collusion between the customer and a company employee to reduce the amount paid to the company (with lower side payments to the employee in return).

HOW CAN ELECTRICITY THEFT BE REDUCED

21

NON TECHNICAL SOLUTIONS

Financial rewards: Utility companies encourage consumers to report electricity theft� Periodic checks: Electricity theft frequently takes place after service has been disconnected. Some utility companies periodically check disconnected meters if the customer has not contacted them to reconnect service.

Enforcement of law: Fines should be imposed by the government for stealing electricity.

22

•Taps, makes or causes to be made any connection with overhead, underground or under water lines or cables, or service wires, or service facilities of a licensee;

•Tampers a meter, installs or uses a tampered meter, current reversing transformer, loop connection or any other device or method which interferes with accurate or proper registration, calibration or metering of electric current or otherwise results in a manner whereby electricity is stolen or wasted.

• Damages or destroys an electric meter, apparatus, equipment, or wire or causes or allows any of them to be so damaged or destroyed as to interfere with the proper or accurate metering of electricity, so as to abstract or consume or use electricity shall be punishable with imprisonment for a term which may extend to three years or with fine or with both.

TECHNICAL SOLUTIONS

Electronic tamper detection meter

Pre payment meters

Plastic meter encasements

Anti theft cable

Using GSM

Using PLCs

24

Electronic Tamper Detection Meters

Automatic detection of :•Meter tamper•Meter Bypass•Meter disconnection

Pre-Payments Meters

• Credit added to the meter on the keypad.• Credit is purchased on the

recharegable token and entered to the meter with disconnection ability

25

Plastic layer

Plastic meter encasements

Anti theft cable

Hard plastic encasements are a type of meter seal. These transparent plastic covers serve as a warning.
