“…Power Quality concerns have many kinds of effects, causes and solutions that may be utilized power to enhance quality and their tool performance. Table 1 discusses the definitions, causes, and impacts of several issues such as voltage sag/swell, transients, voltage flicker, harmonics, voltage fluctuation, noise, voltage spikes, voltage imbalance and power frequency variation [19][20][21][22][23][24][25][26][27][28][29][30].

The state-of-the-art dynamic voltage restorers (DVRs) have advanced significantly in recent years. Modern DVRs can detect voltage sags or dips on the power line in real-time and are able to rapidly inject a compensating voltage to maintain a constant voltage at the load. This helps to improve the power quality of the electrical distribution system and to protect sensitive electronic equipment from voltage fluctuations. One key development in the field of DVRs has been the use of advanced control algorithms that enable the DVR to track the voltage more accurately on the power line and to inject a compensating voltage more accurately. These algorithms can be implemented using digital signal processors (DSPs) or field-programmable gate arrays (FPGAs), which allow for fast and precise control of the DVR. Another important development has been the use of high-frequency inverters in DVRs. These inverters can operate at much higher frequencies than traditional inverters, which allows them to switch on and off more quickly and to inject a more precise compensating voltage. This can help to further improve the power quality of the electrical distribution system. Overall, the state-of-the-art DVR technology continues to evolve, and new advances are being made all the time to improve the performance and reliability of these devices.

“…In [22], most of the events (about 94 %) present a residual voltage equal to 70 % to 90 % and their durations range between 0 ms and 100 ms (5 cycles of 50 Hz). Also, in [24] about 60 % of the voltage dips measured in a 22 kV substation has a residual voltage between 70 % and 90 % and time durations lower than 100 ms.…”

Measurements of Power Quality (PQ) are gaining more importance due to increasing presence of switching power converters that deform the waveform of the distributed voltage further and further away from a sine wave. Especially at medium and high voltage levels, PQ measurements are carried out by means of Instrument Transformers (ITs). A recently started European metrology project, EMPIR 19NRM05 IT4PQ, aims at establishing the methods and procedures for assessing the accuracy of ITs used for PQ measurements. This paper, that is written in the framework of the IT4PQ project, presents a thorough review of the current state-of-the-art of literature and international standards about ITs and PQ. The main results from several papers and the main information from IT and PQ related international standards are summarized.
