STAMI operator can give immediate feedback in case of customer service anomalies
Customer satisfaction improvement
STAMI allows to check the power threshold available to the customer to immediately localize a bad payer
Immediately check defaulting customer
Throw STAMI it is possible to check voltage presence and voltage quality at the supply terminal without involving a crew for verification on field

Main features and tools for the Operation Management Operations
STAMI support daily Low Voltage Network Operations Activity:
In case of LV customer warning call, STAMI operator is able to real time check the condition of the LV network supplying the electronic meter.
Low Voltage Network supervising
In case of LV network fault, STAMI operator may immediately verify the origin of the anomaly and program the activity on field.

Main features and tools for the Operation Management Electricity Regulator Compliance
Throw STAMI It is possible to directly see voltage outages without waiting for documentation
Reliable and immediate data related to LV supply
Quality of service data related to MV/LV TR and LV lines available throw STAMI may be used for reporting
Quality of service monitoring
Thanks to STAMI it is possible to identify LV outages with the exact indication of the beginning and the end

Main features and tools for the Operation Management Energy Balance
Acquisition of load profile and daily consumptions to support fraud detection
Effectively localize energy fraud & theft
STAMI operators are able to perform detailed analysis on the LV network, providing support to the crews in the identification of frauds
By accurate analysis, it allows to identify precisely the customers to be checked on field

Information ViewingIt makes possible to quickly access and
download the results coming from user requests
Data requestUsed to send data requests: it is possible to directly ask about a Meter, a Concentrator, a customized group of meters
Status of transactionsUsed to display all the data requests and to
check their status.
ALVIN ManagementUsed to upload and analyze data coming from
portable energy balance meters (ALVIN)

STAMI: Advanced Metering InterfaceData availability from Electronic Meters
Period, Instantaneous Voltage value, VMIN and VMAX for each phase, number of samples in the allowed range (230V+-10%), number of samples out of allowed range. Electronics meters record a value every ten minutes: 1008 samples a week available.
Voltage Quality
Voltage Outages
Period, onset time, duration of the interruption, affected phase, electric line involved
Monthly consumption
Date, energy consumption value in a billing period on T1, T2 and T3

STAMI: Advanced Metering InterfaceLoad Profile
Active Customer Load Profile: set of graphs available for each meter.
A Load Profile Request returns to the operator a set of graphs with the average active and reactive power consumption profile and, in case of active customers, the active power feeding the grid.
Instead of a graphic representation it is also possible to display the list of the average power consumption values stored in the smart meter every 15 minutes.
It is possible to send a Load Profile request for a single Smart Meter or a whole MT/bt Transformer. In this case STAMI returns the load profile of each Smart Meter, the Load profile, in a unique curve, of the sum of al the smart meters connected to the TR and the load profile of the energy balance meter installed in the secondary substation.
It is possible draw the Load profile of each LV line feed by the Transformer, to create any customized group of meters of which the operator wants to draw the Load Curve, to upload and display the Load curve recorded by ALVIN, the portable energy balance meter.

Probable energy fraudBetween 9.00 am to 6.00 pm the difference between the 2 curves is greater

Metering activitiesRules and Obligations: Italian Timebased Tariff Regulation
Following the introduction of the Telegestore, the Italian Regulator established specific metering rules depending on the characteristic of the customer:
For HV, MV and LV customers with power installed >55 kW it is mandatory a meter reading each hour.
For LV customers with power installed <55 kW the reading is done per consumption timeslots, F1, F2, F3, compliant with the timebased tariff regulation.
