Transformers for Electric Arc-Melting Furnaces with Direct Voltage RegulationJuso Ikanovic
In modern metallurgical and chemical industry there is an
increasing need for electric arc-melting furnaces. Transformer
is also one of the vital parts by which power is supplied to furnaces.
Because of their technological aspects, Electric arcmelting
furnaces, need special transformers different from
usual distribution units. The main problem arises from the demand
for relatively wide range of regulation on the low voltage
side.
In this article one of the many principles of voltage
regulation is described, nomely, low voltage regulation by
means of magnetic flux variations.
The annual report from New England's regional power system operator. The report details the transition happening in New England--away from coal and nuclear and to natural gas to create the electricity needed for the region. Natgas is CRITICAL to New England--and more pipelines are needed to get it there.

In this prentation cognitive radio is described, discussed
and compared with software defined radio (SDR). The two types
of cognitive radio are presented and examples on both spectrum
interweave and spectrum underlay cognitive radio antenna systems
are detailed. Reconfigurable filtennas are proposed as communicating
antennas in a MIMO setting for both cases of cognitive
radio. The benefits of resorting to filtennas as well as toMIMO
configuration is shown and discussed herein. The various antenna
examples are designed, tested and compared with each other. Conclusions
are drawn based on the presented results.
