Technologies have evolved over a period of time
…and so have the meters
11/10/2010 3
Conventional meters
• Meters conventionally measured a single quantity– kWh– kVArh– kVAh
• Meters were used for commercial purpose, (record consumption and bill to consumer)

OverviewSmart 2K Stands for Secure Meters Analysis & Reporting Tool.SMART 2000 is BCS (Base Computer Software) part of Integrated metering system• Energy Meter• BCS ( Base Computer Software)• MRI ( Meter Reading Instrument)
It records energy, electrical parameters, tamper and load survey data. It collects data from the meters using MRI or with modem & telephone line (RMR).These data may be used for analysis and monitoring with the help of Smart 2000 analysis and report tool.Smart 2000 works on Windows platform. Older version working on DOS was Sems Pack.
11/10/2010 37
Gives logical view of all the meter reading data according to various parameters like:• Instantaneous parameter, • Current energy & bill energy data, • Time of day energy register data, • MDs, • Abnormal electrical condition data
Perform various other operations called transactions on the meter like Authenticated MD reset, update Date & Time, Tariff, etc.Organized storage of meter reading data and consumer data.New user(s) with their level of access rights could be defined and / manage by supervisor based upon their usage.
Features

Features (Contd…)
Exporting the meter data in the industry standard common formats (like ASCII, CSV) so data can be used by other software for billing or otherwise.
Load survey information is displayed graphically whereby user has an option to see multiple parameters on the same graph or on a separate view.
All the information displayed on the screen can be printed and permanent record can be maintained.
Customer can choose what is to be printed. Selection
• on category such as Energy, Survey, Transaction, etc
• or on subcategory such as Main energy, Bill energy, TOD energy, history of energy registers etc.
