MSSB to Prevent Cable Termination Faults for Long High Voltage Underground Cable Lines

open access: yesElektronika ir Elektrotechnika, 2019
Cable termination fault is one of the most important problems for high voltage underground cable lines (HVUCL). Harmonic current (HC) and the sheath current (SC) are causes of cable termination faults of HVUCL.

Behavior of single-point harmonic producer indicators in electrified AC railways [PDF]

open access: yesMetrology and Measurement Systems, 2021
Electrified railways are an example of AC single phase distribution networks. A non-negligible amount of active and nonactive power may be related to harmonics, especially for distorted highly-loaded systems.

Robust H8 design for resonant control in a CVCF inverter application over load uncertainties [PDF]

open access: yes, 2020
CVCF (constant voltage, constant frequency) inverters are electronic devices used to supply AC loads from DC storage elements such as batteries or photovoltaic cells. These devices are used to feed different kinds of loads; this uncertainty requires that
