Low-voltage DC (LVDC) grids offer an attractive way forward in reducing conversion losses and simplifying local power management. However, ensuring reliable operation depends on a thorough understanding of DC distortions\u2014phenomena generated by power converters, source instability, and varying loads. Two complementary traceable measurement chains are presented in this article with the purpose of measuring the steady-state DC component and the amplitude and frequency of the distortions around the DC bus with low uncertainties. One chain is optimized for laboratory environments, with high effectiveness in a controlled setup, and the other one is designed as a flexible and easily transportable solution, ensuring efficient and accurate assessments of DC distortions for field applications. In addition to our hardware solutions fully characterized by the uncertainty budget, we present the measurement method used for assessing DC distortions after evaluating the limitations of conventional AC techniques. Both arrangements are set to measure voltages of up to 1000 V, currents of up to 30 A, and frequency components of up to 150\u2013500 kHz, with an uncertainty varying from 0.01% to less than 1%. This level of accuracy in the measurements will allow us to draw reliable conclusions regarding the dynamic behavior of future LVDC grids.<\/jats:p>","DOI":"10.3390\/s25196043","type":"journal-article","created":{"date-parts":[[2025,10,1]],"date-time":"2025-10-01T09:37:21Z","timestamp":1759311441000},"page":"6043","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Exploring DC Power Quality Measurement and Characterization Techniques"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2738-3515","authenticated-orcid":false,"given":"Yara","family":"Daaboul","sequence":"first","affiliation":[{"name":"Laboratoire National de M\u00e9trologie et D\u2019essais (LNE), 78190 Trappes, France"},{"name":"GeePs, Laboratoire de G\u00e9nie Electrique Et Electronique de Paris, CNRS, CentraleSup\u00e9lec, University Paris-Saclay, Sorbonne University, 91190 Gif-sur-Yvette, France"},{"name":"EDF\u2014R&D, Electricit\u00e9 de France, 91190 Saclay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2825-1317","authenticated-orcid":false,"given":"Daniela","family":"Istrate","sequence":"additional","affiliation":[{"name":"Laboratoire National de M\u00e9trologie et D\u2019essais (LNE), 78190 Trappes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5563-9192","authenticated-orcid":false,"given":"Yann","family":"Le Bihan","sequence":"additional","affiliation":[{"name":"GeePs, Laboratoire de G\u00e9nie Electrique Et Electronique de Paris, CNRS, CentraleSup\u00e9lec, University Paris-Saclay, Sorbonne University, 91190 Gif-sur-Yvette, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ludovic","family":"Bertin","sequence":"additional","affiliation":[{"name":"EDF\u2014R&D, Electricit\u00e9 de France, 91190 Saclay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xavier","family":"Yang","sequence":"additional","affiliation":[{"name":"EDF\u2014R&D, Electricit\u00e9 de France, 91190 Saclay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"293","DOI":"10.1049\/oap-cired.2017.0519","article-title":"LVDC rules\u2013Technical specifications for public LVDC distribution network","volume":"2017","author":"Nuutinen","year":"2017","journal-title":"Cired.
