Here, the primary neutral must be available. With this system, you can use 2,400V, single-phase transformers, resulting in a cost savings over 4,160V, single-phase transformers. The secondary voltage ...

ABB has successfully tested and delivered three 750-MVA (765/500/13.8 kV), single phase auto-transformers designed and built for the U.S.-based electric utility, Allegheny Energy. The transformers ...

In early 2019, a Dissolved Gas Analysis (DGA) was performed on all three single-phase 500 kV: 115 kV transformers at Tono Substation. One of the transformers was identified as nearing its end of life ...

For example, single-phase voltage sags applied to Phase B or C had no affect on the connected loads, even when the applied voltage dipped to zero volts. Simultaneous sags and interruptions of Phases B ...

Munich, Germany – The new IRS260xD family of high speed power MOSFET and IGBT drivers offers optional dependent or independent high- and low-side referenced output channels with a gate drive supply ...

At light loads and high ac-mains voltage, a wall wart may provide efficiency approaching 90% but a power factor of only 60%. At heavy loads and low ac-line voltage, efficiency may be less than 75%, ...

International Rectifier has released the IRS260xD family of single-phase high voltage ICs for motor drive applications including air conditioners, fans, pumps, micro, mini and general purpose inverter ...
