CLASSIFICATION OF HIGH IMPEDANCE FAULTS, INCIPIENT FAULTS AND CIRCUIT BREAKER RESTRIKES DURING CAPACITOR BANK DE-ENERGIZATION IN RADIAL DISTRIBUTION FEEDERS
… events can cause unsafe operation, including a high impedance fault (HIF) caused by a downed conductor touch ground surface, an incipient fault (IF) caused by partial breakdown to a cable insulation, and a circuit breaker (CB) malfunction due to capacitor bank de-energization to cause current …

Case study comparisons of standard and energy efficient polyphase induction motors subjected to unbalances phase voltages
… phase voltage conditions by assuming a high impedance fault at the motor terminals. In this study, a method is used to simulate unbalanced phase voltage conditions by varying the phase voltage at one of the motor terminals. The nonlinear variation of motor impedance with frequency is …

Protection of Falling Conductors into Flammable Vegetation Faults
… into detecting a single line open circuit fault. The open circuit is momentary and hence, speed is of the essence in such a protection scheme. In this thesis, detection of an open circuit is carried out in two different ways, viz., with and without communication support between the various …

High Impedance Arc Fault Detection in a Manhole Environment.
… scope of this thesis was to develop a prototype high-impedance arc detection system that a utility worker could use as an early warning system while working in a manhole environment. As part of this system sensors and algorithms were developed to increase the sensitivity of detecting an arc while …
