Simulation data illustrating emergence of ferroresonance processes in medium- and high-voltage electrical networks are reported. Cases, most frequently met in practice, in which ferroresonance oscillations arise, are addressed. Typical oscillograms depicting simulated phenomena are presented. Based on the data obtained, measures aimed at preventing possible(More)

In this paper, the results of atomic power plant (APP) house system operation modes analysis, the selection of the optimal value of the neutral point grounding resistance of the network, the selection of the place for the special neutrals assignment transformer installation, to which the resistors are connected as well as the capabilities of parallel(More)
New design and results of testing of a broadband microwave tunable delay line are presented. A tunable delay line on the basis of microstrip broadbanded directional couplers and tunable reflective terminals with ferroelectric film planar capacitors was created. The delay variation of 1 ns over frequency range from 1.8 GHz to 2.2 GHz was exhibited.
