Nowadays, the interest in low-cost and increasingly accurate phasor measurement units
(PMUs) for active distribution systems is steadily growing. In this paper, an algorithm for …

With the proliferation of harmonic sources in power systems, current transformers (CTs),
which are the most widely used current transducers in power systems, will have to measure …

The paper presents a method for the frequency characterization of voltage transformers
(VTs) for medium voltage (MV) grids which involves only sine waves. It is called extended …

In the context of modern power systems, where there are lots of non-linear loads and
generators based on switching power electronics, the accurate measurement of voltage and …

In the new electrical system scenario, the increasing presence of non-linear loads and
