Electric Meters with our

Smart Self Managed Metering System

IUSA, a company with more than 70 years’ experience devoted to

innovation and development of technologies in metering and com-

munications, has created an innovative system for the efficient ope-

ration and management of the process of metering and marketing

electrical energy: the Smart Self Managed Metering System.

Description

The IUSA Smart Self Managed Metering System was created with the aim of making customer service processes more efficient and lowering financial and operative costs of electrical energy distribu-tion or utility companies, while giving users control over their usage and offering them more accessible forms of payment.This system is patented internationally and operated by means of a multifunctional electronic meter, a two ways smart card, and a software that administers the process.It has a two ways user-utility communication, which allows the ope-rator to “monitor” the user and to obtain statistics on frequency of use, usage, and other technical information useful for the utility. Also, the utility can program functions in the meter through its smartcard. Its security system secures and reliably protects all essentialinformation for users and the utility.

Payment Mode

One of its advantages is that it can operate in prepayment or post payment mode and is easy to administer, given that both modes are configured using the smart card.In prepayment mode, the meter informs the user that the balance isrunning low by means of a visual alarm, a blinking led.The user goes to the nearest point of sale with his card to buy electrical energy. There, the user requests the number of kilowatt hours he wants to buy and makes the appropriate payment. Pointsof sale are located in areas near users and have very ample busi-ness hours. The user can also choose to recharge his smart card through Internet, by means of a card reader. When the balance hasbeen credited to the card, the user can set it on top of the meter andtransfer the balance, which will then allow him to use the electric energy.In post-payment mode, when the utility’s present usage cycle ends,the user must set his card on top of the meter to record his usage.The meter will display the usage of the past month in kWh and theamount due in monetary units.

The user takes his smart card to a point of sale to pay the cost of his usage. He may also make his payment through Internet. Then, the user must return to the meter and set the smart card to inform itof the payment and avoid suspension of service

Description of the Multifunction Energy Meter

This meter was developed and is manufactured in Mexico with the highest standards of quality and leading edge technology at IUSA’s plants located in Pasteje, State of Mexico, and therefore it is con-sidered a precision instrument for application in metering electrical energy. Its design and the materials used, guarantee reliable per-formance over time.It also has a Smart Self Managing Device that works with rechar-ges, usage, and balances built into the meter display, which in-teracts with a contactless rechargeable card, which is capable of communicating with the meter without the need for additional hard-ware devices or slots.The card can be configured to partially or totally download the balance to the meter, allowing the user to closely administer his electric usage. Also, it has options of a real time clock to record monthly usage, as well as recharge dates, service cutoffs, peak demand times, etc. It has an optical port, which allows for readings from the meter, cutoff and connection, time configuration, and trial mode configuration.Regarding the means of supplying or restricting electric energy, themeter is configured to perform those functions in manual or auto-matic mode. In manual mode, the user can disconnect and recon-nect energy with the smart card whenever he wants. If the meter isset on automatic mode, the meter itself will connect energy when it has a balance or credit in its memory and will cut off the service when it runs out. In addition, a level can be set for each user, with flashing LEDs and/or prepayment screens to give the user a visualnotification that he needs to purchase more electric energy.

Measurements and Reports

Multifunction Meter is able to execute the following measurements:

1.- Energy: (U) Unidirectional Energy (B) Positive and Negative Energy

2.- Reactive energy: (U) Reactive. (B) Reactive quadrant 1 Q1, reactive quadrant 2 Q2, reactive qua-drant 3 Q3 and reactive quadrant 4 Q4.

3.- Demand:• (U) Maximum Demand Total.• (B) Maximum positive demand and maximum negative demand.

(TOU) Time of Use. The Multifunction Meter can use TOU to get all the previous mea-surements for 4 periods and for 4 different rates.

Billing period. The maximum billing period for a Multifunction Meter is =< 1 month.

Reports.• The Multifunction Meter saves in its memory the following information: a) User consumption at the end of month. b) User consumption at the end of period. c) Events. d) See the Event Chapter. e) Statistics.

Technical Specification Multifunction Electronic Single Phase Meter CP-11-B1

• The Multifunction Meter can get monthly statistics for: a) Maximum Voltage. b) Minimum Voltage. c) Monthly Demand.

Contactless Two Ways Smart Card

Information (readings, charges, profiles, etc.) is transferred by means of contactless cards, which offer greater efficiency by eli-minating the need to introduce codes or cards in the meter. Each user receives a unique and permanent card that is linked to his meter. This card’s communication with the meter is in two ways. This means that information can be transmitted from the card to the meter and from the meter to the card simultaneously, with no res-triction on the number of operations, and above all, with no contactbetween them. This communication is carried over a RFID inter-face.The card incorporates the strongest security measures to prevent duplication or misuse, with all the data stored on it encrypted with security standards like those of the banking system.

Management Software

The system includes a management software that is installed at the utility’s branch offices or authorized points of sale. The functions that can be performed using this software include: Sale of kWh. Replacement of lost cards. Registration, cancellation, and change of users. Restore misplaced sales. Generate reports. Configure meter operation. Configure rates applicable to sales. Administer system operators by means of authorization levels.

Features and Benefits of the IUSA Smart Self Managed System: Contactless two ways communication card. Two-ways communication. User autonomy in service payment. Exchange of data and creation of databases to generate statistics

and reports on: Consumer profiles. Tampering detection. Sales. Total control of supply and automatic suspension or restriction of

service. Replacement of lost cards. Only one card per meter. High security levels. Configurable rates for sales. Hourly rate for 4 seasons and 4 periods for active and reactive

energy using a clock. Load profile every 15 minutes during a month. Monetary unit record of the previous and current month energy

usage based on the utility´s rates. Multi-operator management software. Lower operative and administrative costs.

Advantages of the System

Users Total control of electric energy usage. Flexibility that allows the user to decide when and how much to

buy. Convenience, because services can be purchased at authorized

establishments near the user’s home, with convenient business hours and without the need to wait in line. Also payments and pur-chases of energy can be done through Internet. Security, because the smart card is nontransferable and works

only with the meter to which it is assigned.

Utility Guarantees revenue from advanced and on time payment of

electric sales, with the financial benefits it entails, completely elimi-nating delinquent users and bad accounts. Lower administrative costs; expenses related to periodic readings,

as well as bills issuance and distribution, disappear completely.Consequently, the number of users attended at the utility’s offices is reduced considerably. With the online management software IUSA has developed, utility

executives will be able to access all kinds of information and re-ports designed in accordance with their needs. Electric sales, num-ber of recharges, value of recharges, consumer profiles, demand profiles, suspension for lack of balance, electric outages, failure reports, and tampering will be reported to service providers. The field information reported by the system will allow them to make better decisions to control, analyze, plan, and administer the servi-ces they provide.

The IUSA Smart Self Managed Metering System is unquestionably the most innovative solution

for electric energy marketing.
