Guidelines for combining different single-mode fibre sub-categories
IEC TR 62000:2021 provides guidelines concerning single-mode fibre inter-compatibility. A given category of single-mode fibre, for example B-655, can have different implementations by suitably optimising several of the following parameters: mode field diameter (hence effective area), chromatic dispersion coefficient, slope of the chromatic dispersion curve, cable cut-off wavelength. These…
Electrical energy storage (EES) systems - Part 2-200: Unit parameters and testing methods - Case stu...
IEC TR 62933-2-200:2021(E) presents a case study of electrical energy storage (EES) systems located in electric vehicle (EV) charging stations with photovoltaic (PV) power generation (PV-EES-EV charging stations) with a voltage level of 20 kV and below. EES systems are highlighted in this document because they are a desired option to make the charging stations (especially the high-power fast…
