WHAT is WHAT is AMRAMR????
Automatic Meter Reading– Automating the process of
measurement and control through digital communication techniques.
– Bring “intelligence” into the revenue cycle and manage it.
Metering Billing Operations Customer Service
National Power Training Institute(NR)
WHY AMR NEEDED in place of current Stand-alone meter reading??
Present System Problems:- Highly Person dependant. Human errors cannot be avoided. Accessibility of meters in rural/ Agricultural zones. Energy Audits performed based on bill collection which is
highly inaccurate. Billing done mainly on estimated/ monthly average basis Inability to monitor and control discrete loads Billing cycle requires excessive time. Meter data used only for billing, cannot help in analysis like
demand analysis, energy audit, pinpointing losses, etc.

Benefits of AMRBenefits of AMR
Ability to detect tamper events and outage occurrences. Remotely Connect/ Disconnect power supply through
meter. Calculate Transformer loading and Sizing from interval
data. 15 minute interval data gives accurate load information for
supply scheduling, switching operations, planning etc. Monitor voltage at each premise to know conditions when
to operate capacitor switches or regulators. Consistent and Granular data for improved accuracy.

– The AMR system starts at the meter. Some means of translating readings from rotating meter dials, or cyclometer style meter dials, into digital form is necessary in order to send digital metering data from the customer site to a central point.

PREPAID METERS-AdvantagesPREPAID METERS-Advantages
For meter owner Assured revenue and reduced working capital costs Lower overheads Better load management and higher capacity utilization Improved fraud detection Quicker connections and better customer-service
For end-consumer Better budgeting Promotes energy savings and energy conservation Avoid long queues – choose when to pay No billing errors Convenient mode of payment

System at workSystem at work
The consumer inserts the pre-paid card in the energy meter
The value (Credit + Any information) in the card is transferred to the meter
The meter keeps track of the number of units consumed as per the slab rate
When the value in the meter comes to 10-20% a signal is given -either beep or red light
When the value in the meter becomes nil the electricity supply is cut off
National Power Training Institute(NR)
ApplicationsApplications
Large-scale deployment by utilities for residential andcommercial connections
Sub-metering in apartments, shopping malls andbuilding complexes.
Convenient mode of payment in housing colonies As a second meter between utility meter and
distribution board for housing tenants Selective deployment by utilities in regions with poor
credit history Electricity supply for vendors, contractors and temporary
connections
