Ship service electrical power consumption at the shore side has rapidly grown for commercial ships. The environmental impact of the pollution created while at berth has many ports restricting the operation of on-board generators. Shutting off these on-board generators and supplying ship's power from the shore power system can reduce the air pollution emissions. With the development of medium voltage...
The following topics are dealt with: EMF technical standardization; radar cross section; grounding from chips to systems; EMC measurement; antennas; power line communications; grounding; EMC test methods and standardization; EMC in aerospace and avionics systems; electrostatic discharge; EMC in systems and equipment; EMC test equipment and facilities; emissions and immunity; interference and propagation...
AC railway systems operating at high voltage (20, 25 or 50 kV) and network frequency (50 or 60 Hz) are currently the best choice for new track design, thanks to their reliability and efficiency. However, AC railway systems are connected to the national power grid by single phase power transformers and consequently the three phase voltage vectors on the public system become unbalanced. Moreover, AC...
The authors examine the differences between static and dynamic short-circuit analyses by comparing the results of each for a specific industrial power system. The static method used is that of ANSI C37.XX, which essentially calculates short-circuit duties of static points of time. The dynamic method, which is data-intensive, calculates the value of short-circuit currents for any time from fault incidence...
