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.
