Intelligent over-current protection scheme in inverter-based microgrids
2015 Smart Grid Conference (SGC), 2015Recently by technological developments in inverterbased devices, application of these prominent apparatus has gained more attention in newly emerged microgrids (MGs). In this paradigm, the concept of multiple inverter-interfaced distributed generations (IIDGs)-based MG is now a reputable term.

New over current protection technology addressing DC Transportation
2016 IEEE Transportation Electrification Conference and Expo (ITEC), 2016Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC, have brought conventional current limiting devices to their limits. Indeed, mechanical circuit breakers may be too slow to open for networks with large DC fault currents. On the other hand, fuses may be too slow

Adaptive over current protection for distribution feeders with distributed generators
IEEE PES Power Systems Conference and Exposition, 2004., 2005The connection of distributed generators (DG) to distribution networks influences the performance of the networks. This paper focuses on the impact of DG on the feeder protection, specifically the impact on the overcurrent (OC) relay performance. The paper presents simulation results to show the extent of deterioration a DG can cause on the OC relay ...

Study of Over-Current Protection, Electric Arcing, and Fire Prevention
51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010The contribution of electrical wiring to ballistic threat-induced aircraft fires is a recognized, but poorly quantified vulnerability, particularly as modern aircraft continue to evolve. Electrical systems are increasingly replacing or supplementing mechanical systems.

Improving the performance of smart grid over-current protection relays
2011 IEEE PES Innovative Smart Grid Technologies, 2011Due to the significant increase in non linear loads and the worldwide trend to establish smart grids, harmonic level in the electricity grids is significantly increased. In addition to their impact on power quality, harmonic currents can have a devastating effect on power system protection performance especially on the operation of over current relays ...

Design of over-current protection circuit for digital power amplifier
2016 International Conference on Emerging Trends in Electrical Electronics & Sustainable Energy Systems (ICETEESES), 2016This work shows a modified excess current preservation circuitry for digital power amplifier. Excess current is a condition when a greater than required current occurs, which will be dangerous for our instrument. This preservation circuitry is useful to cut off the output buffer when two output pins short-circuit to Vcc, short-circuit to Gnd or short ...
