Sentence examples for large power transformers from inspiring English sources
Disk type windings are widely used in large power transformers.
A variety of arrangements of windings in large power transformers are described.
Significant power grid impacts in present day networks have been observed at relatively low levels of intensity, for example the Quebec grid blackout during the March 1989 storm occurred at a peak intensity of ∼480 nT/min and permanent damage to large power transformers have occurred at even lower intensity levels.
SPX, of Muskegon, Mich., is wildly popular with analysts as it sheds auto parts and industrial controls to remake itself into a zippy miniconglomerate selling large power transformers, TV transmitters and industrial mixers.
Large power transformers are vulnerable to insulation failure due to transient voltages with high-frequency components, such as caused in switching or by lightning.
Large power transformers use multiple-stranded conductors as well, since even at low power frequencies non-uniform distribution of current would otherwise exist in high-current windings.
Up to recently, the tank for a large power transformer or a shunt reactor was typically designed to withstand vacuum filling, transportation and sometimes earthquakes.
Larger power transformers operating at high voltages may be wound with copper rectangular strip conductors insulated by oil-impregnated paper and blocks of pressboard.
Even today, a typical stereo amplifier is dominated by a disproportionately large power supply, transformer and array of heat sinks.
Determination of partial discharge locations in large oil-filled power transformers is unreliable and difficult using external acoustic sensors, and internal sensors would need to be non-metallic.
Wind parks are made up of a large number of saturable inductances (power transformers, inductive voltage transformers (IVTs)), as well as capacitors (cables, wind turbine harmonic filters, capacitor voltage transformers (CVTs), voltage grading capacitors in circuit-breakers).
