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.

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

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.

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.
