Technology Trends in Metering
2
The Need.
The Transmission, distribution and commercial
losses in LT distribution system account for a
loss of revenue to the tune of 38 on an average
in the country. Of these, 8 are acceptable
technical losses whereas 30 of the losses are
recoverable commercial losses.

Present Scenario

• Intelligent Multifunction Single Phase metering
  with Anti Tamper features
• Intelligent Multifunction Three Phase Metering
  with Load Surveys and Anti Tamper Features

4
New Concepts in Metering

• RF Enabled Single Phase Metering
• Post Paid Metering System with Disconnection
  facilities
• DT metering coupled with Automatic Metering from
  the meters connected to that particular DT
• Dual Metering
• Closed Loop Metering

5
RF Enabled Single Phase Meters

• Present Status
• Meters with Optical Port
• Meters with IR/IRDA Port
• Present Need
• Meters with RF inbuilt module so that the
  readings can be taken directly from the meter
  reliably without opening the Box
• Common Protocol so that the reading devices are
  common

6
Post Paid Metering With Disconnection facilities

• Present Status
• Pre Paid Meters with relay are available
• Complex Tariff structures makes it difficult to
  program
• Difficult Vending Systems
• Need
• The post paid system is quite established and
  needs to be coupled with a procedure which allows
  for self billing
• In case the payment is not received by utility
  then the meter should recognize the same and
  should disconnect the supply

7
Automatic Metering

• Lots of efforts are on but are limited to three
  phase meters and at best to Feeder and
  Distribution Transformers
• Need is to integrate the Single Phase and Other
  metering units so that a seamless metering can be
  done from Feeder Metering to the domestic
  metering to get the true Auditing and true
  calculation of losses

8
Dual Metering

• Presently lots of consumers are getting supply
  directly from the Utilities as well as from the
  DG sets installed and run by local contractors
• Being different in terms of tariff patterns the
  need is to introduce Dual Meters which can have
  dual measurement channels and can measure and
  different the consumption patterns

Closed Loop Metering
10
Identifying the Defaulter
11
Points to Take Home

• This system shall be a end to end energy
  management solution for Distribution Auditing
  monitoring thereby driving the utilities revenue
  to a higher level.
• Real time monitoring of the whole distribution
  systems viz. DT transformer, feeders, and
  consumers and can be visually pinpointed on a GPS
  map.
• The system will be highly cost effective and
  contributes to a very efficient AMR solution.
• The system is immune to human error of omission
  and commission.

Benefits- To the Utility

• Big savings due to avoidance of thefts and
  pilferage
• Reduced meter reading costs Saving Meter
  Readers, Accountants, Billing cost indirect
  Cost.
• Enable automatic update of the system without any
  additional costs

13
Benefits- To the Utility

• Improve customer service by
• providing timely and accurate bills, automating
  outage notification
• Eliminating manual reads
• improving the process of resolving meter reading
  disputes.
• Implementation of real-time pricing by use of TOU
  metering and time synchronization of meter RTC
  with internet time server.

14
Benefits- To the Utility

• Possibility to give statistical information for
  power consumption of each region and on the base
  of this information Electric Power Company has
  possibility to plan and develop the system.
• Ability to use GIS (Geographic Information
  System) map that enables utilities to see
  location of each meter and through it to receive
  history for energy consumption.

15
Benefits- To the Consumer

• Accurate billing statements and improved service
  due to fully automization and online connectivity
  of meter.
• Improved security because the meter readers no
  longer need to gain access to the property

16
Benefits- To the Consumer

• Better analysis and reporting of power
  consumptions and power factor.
• Provide Quality Power to the consumers by
  instantly detecting the tampers, MD shoot ups,
  Load customer Load Profiles.
