Class1 accuracy meter for the entire load curve.

Anti theft Features presently availableReverse CurrentEarthed LoadNeutral Missing

LCD Display for Multiple Display

Maximum Demand for last 4 to 6 months

TOD( Time Of Day ) feature

Optical communication for Data Downloading.

Existing Electronic Energy Meter

Difficulties Experienced with EEMGlow of Earth LED due to wiring problems.

Reading Difficulty (due to the constraints of meter mounting).

Tampering by Opening the Meter & Fixing external components.

Manual billing cycle (resulting in delays of payment cycle).

No Direct Disconnection of consumer services.

Difficult to Monitor the energy consumption patterns.

Need of the Hour

� Energy Distribution Model === Telecommunication Model

� Use of Information Technology

� Quality uninterrupted power to genuine users

� Improving the revenue recoveries

� More stringent Metering strategies

Other Requirements

Auditing the Energy supplied. (with Energy consumed)

Automatic reminders to consumers.(encouraging the proper use of Electricity and Payment options)

Installation and Maintenance ease.

Common Data base. (Meter reading & billing software)

Low cost

Existing Availiable SolutionGSM Modem ( for Getting the data on regular intervals )

Infrared based single phase meters

Meters with RF Modems

Multiple Meters in a Box with common Display units

Pre Paid Meters & Inter Operable Software

Split Display unit with Additional wires for communication

LimitationsHigh cost of Modems ( In most of the case more than the cost

of metering equipment)

Consumer Fiddling in premises, if mounted inside.

Consumer can legally challenge, if mounted outside (As he is

entitled for viewing his consumption patterns )

No control over the payments

No automatic disconnections

Proposed Solution

Meter Installation away from the consumer and preferably on a pole top or road side distribution box / Common Metering CabinsConsumers provided with a Display unit with PLCC Modem so that the readings only are accessible to the consumerGrouping the Meters in a Common box and providing single common GSM/GPRS /CDMA Modem for getting the online DataMeasurement of energy in Phase only thereby reducing the cost and improving reliability by reducing the number of componentsMaster Meter for keeping audit recordIndividual latching relays for remote connection and disconnectionStandard Common Internationally accepted Protocol

Proposed Group Metering Solution

(A) MODULAR METERS,PLCC MODEM & GSM MODEM10 Nos. configurable Meter Modules Master summation Meter for Audit PurposeRemote Energy Display UnitPLCC and GSM/GPRS Modem

(B) PCB TYPE METERING MODULES,PLCC & GSM MODEM18 Nos. configurable Meters on a Mother Board PCB. (With accumulator) Connect-disconnect feature using latching relay 100AMaster Summation MeterRemote Energy Display UnitPLCC & GSM/GPRS Modem

Why Grouping the Meters

Concept of Group meter: Bringing out the meter from the consumer premises to the distribution pole and preferably at a certain heightDifficult to access the meters: Due to the Group of meters sealed in an enclosure since they are mounted in a common distribution boxConsumers display unit(REDU): Residential Energy Display UnitCommercial benefits: The cost of the main Modem fitted inside the distribution box gets divided into 10 consumers.

Special Advantages

Cost Amortization : Accumulator, PLCC Modem, Master Summation Meter, GPRS Modem(10 or more no. of users)Complete control: Standard Latching relay units for Remote connection and disconnection of the supplies. (on individual basis or based on a software application/ can be linked to the payments and tampering alarms) Social benefits: The Modems can be used to display real time information to the consumerTampering to be reduced drasticallyModular concept: 10 metering modulesSpace Saving: approximately 40% ( for 10 Modules)(useful for apartments and dense areas)No BY PASS : Meter Incoming is fully Protected Non Possibility of Power reversal, Neutral cut, Earth Load Tamper

SPLIT DISPLAY UNIT BASED ON PLCC TECHNOLOGY

GSM/GPRS MODEM

Composite Metering Unit

Data Collecting Software(URJA)

Applications

Heavy theft prone cluster areas: where the conventional metering is not successful and the concept can be extended to normal apartment meters as well

The system can be utilized as Check meters

The Group metering system can be directly mounted on HVDS transformers of 25 KVA type and can be used for supplying and metering electricity to one unit

Projects & CustomersSuccessful implementation at Columbia and Brazil with remote disconnection feature. A pilot project of 850 No of Group Metering is underway at NDPL Delhi where the meters are directly fixed on the HVDS transformers

Dual Chamber10 ModulesRF /GPRS Modem for remote data transferSummation MeterPLCC based Display Unit

Regulations

The regulatory bodies: Encouraging the system and clearance for the project implementation The BIS: Appreciated the concept and setup an Intellect Working Committee to finalize the StandardsThe present Metering standards: Followed for the Measurement purpose in the individual metering modules

Scientific and Technical AdvancementDevelopment of cluster metering and associated technologiesDevelopment of highly integrated end to end energy measurement/auditing/management solutions to the utilities.A step in the direction of increased technology convergence

Summary of Project Benefits

Highly accurate and better than 1% AccuracyReal time Data availability thru GPRS ModemsTamper Alarms and immediate information to the serverUse of International standard IEC DLMS protocols for having a common Data Polling and monitoring softwareLow cost as the Cost of Modems get amortized over a number of MetersOnly display Units at consumer premises without additional wiresReminder Option for payment etc. thru the Modems on the consumer display unitsRemote connection and disconnection facilitySummation metering for auditing purposeNo Possibility of manipulationModular Concept
