Monitoring of voltage quality

AiLux installs the MP3G apparatus for monitoring the quality of the voltage and the micro-interruptions that meets the requirements of Article 23 that responds to the Terna specification “Technical monitoring of micro-interruptions technical specification rev. 1.0 of 31/03/2016 “. It offers the AT / AAT customer the opportunity to make use of the regulations in his favor, which will establish AEEGSI, following his participation in the campaign to monitor the quality of the voltage. The monitoring campaign will have as its object the “micro-interruptions”, ie voltage holes and transient interruptions (interruptions with a duration of <1 second).

WHY ARTICLE 23:

It offers the AT / AAT customer the opportunity to make use of the regulations in his favor, which will establish AEEGSI, following his participation in the campaign to monitor the quality of the voltage. The monitoring campaign will have as its object the “micro-interruptions”, ie voltage holes and transient interruptions (interruptions with a duration of <1 second).
The AT / AAT user wishing to participate in the monitoring campaign will have to equip himself with a measuring and monitoring device that responds to the Terna specification “Technical specification micro-interruption monitoring devices rev. 1.0 of 31/03/2016 “and report to the same the intention a
participate. The characteristic parameters of the quality of the voltage are:

• the frequency
• the amplitude and the variations of the tension
• voltage holes
• interruptions
• overvoltages
• the harmonic distortion of the voltage
• short-term and long-term voltage fluctuation (flicker)
• degree of asymmetry of the three-phase voltage

HOW WE DEVELOP THE INFRASTRUCTURE FOR ARTICLE 23:

The communication of measurement data recorded by our equipment to the TERNA Central System, is based on spontaneous sending (push) of files in PQDIF format through secure https sessions with a central communication server. Terna will set up a web-service that you can reach using the https protocol from the Internet and which provides two authentication modes, with one or two factors, more precisely:

• Authentication based on username and password (in this case Terna will deliver one user for each equipment to be configured). The password must never be stored in clear text in the instrument PQ or in the software.
• A second additional authentication factor, consisting of a digital certificate (in this case Terna will deliver a digital certificate issued by its PKI for each PQ tool to be configured).
