IEEE Draft Standard for Requirements for Pad-Mounted, Compartmental Type, Self Cooled, Three Phase Distribution Transformers, 10 MVA and Smaller; High Voltage, 34.5kV Nominal System Voltage and Below; Low Voltage, 15kV Nominal System Voltage and Below

Certain electrical, dimensional, and mechanical characteristics are set forth as well ascertain safety features of three-phase, 60 Hz., mineral-oil-immersed, self-cooled, pad-mounted,compartmental-type distribution transformers. These transformers are rated 5 MVA and smaller,with the high voltage limit of 34.5 kV system nominal voltage and below, and with low voltage limitof 15 kV system nominal voltage and below. […]

IEEE Approved Draft Standard for Metal-Enclosed Low Voltage (1000Vac and Below, 3200Vdc and Below) Power Circuit Breaker Switchgear

  Low-voltage metal-enclosed switchgearwhich contains either stationary or drawout, manually or electrically operated low-voltage ac or dc power circuit breakers in individual metal compartments, in three-pole, four-pole, two-pole, or single-pole constructionis covered. Rated maximum voltage levels are 254 V, 508 V, or 635 V, 730 V, or 1058 V ac and 300/325 V, 600 V, […]

Editorial: IEEE Transactions on Power Electronics, February 2015

    In this paper, a single-phase, single-stage current source inverter-based photovoltaic system for grid connection is proposed. The system utilizes transformer-less single-stage conversion for tracking the maximum power point and interfacing the photovoltaic array to the grid. The maximum power point is maintained with a fuzzy logic controller. A proportional-resonant controller is used to […]

CEA’s 4K Ultra HD Logo Program [CEA Insights]

The Consumer Electronics Association (CEA) announced in November the availability of new 4K ultrahigh-definition (UHD) logos for use in identifying display products that meet CEA?s 4K UHD voluntary core characteristics. CEA is providing two logos for use (Figure 1)?4K UHD and 4K UHD Connected??available to manufacturers via a licensing agreement for product packaging, marketing materials, […]
