Present Status of LT Energy Metering in Present Status of LT Energy Metering in DomesticDomestic

• To measure energy various Utilities still uses Electro mechanical meters and low cost digital meters with accuracy class is 1.0 above.

• Line loss rate is estimated to be much beyond 20% due to tampering.

• Readings of the meter is done manually that leads to obvious error and wastage of time and resource.

• It is difficult to make exact load consumption analysis.

Issues with Other Communication NetworkIssues with Other Communication Network

• Highly depends on other mobile network.

• Accessibility of Mobile network in remote areas is not available.

• In many cases manual reading is also not feasible.

• Billing cycle requires excessive time.

• System Maintenance is very expensive.

Critical Benefits from PLCC CommunicationCritical Benefits from PLCC Communication

• Most economically viable technology for transferring Meter Data to DCU.

• Using this technique of communication the data can be transferred over the existing LT Power lines.

• Narrow Band Direct Sequence Spread Spectrum Power Line Carrier Communications Technology.

• Encryption is provided for, to ensure the data accuracy, integrity and security.
