IET Generation, Transmission & Distribution, 2021
The main protection equipment in radial distribution networks are non-directional overcurrent relays (NDOCR) and fuses which are coordinated using the conventional protection coordination method. By installing distributed generations (DGs) in the network,

Analytical Estimation of MMC Short-Circuit Currents in the AC In-Feed Steady-State Stage
IEEE Transactions on Power Delivery, 2021Modular multilevel converters (MMCs) are vulnerable to DC short-circuit faults. Analytical estimation of the AC and DC short-circuit currents in the AC in-feed steady-state stage is essential to reveal fault mechanisms and design protections.

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981
Short circuit thermally stimulated discharge [TSO) has been used as a technique to study trapping characteristics of a material(1). We have in mind experiments in which the sample is initially poled under constant applied voltage V 0 through an ohmic contact, until a steady state current i S is reached.

Improved MPPT short-circuit current method by a fuzzy short-circuit current estimator
2011 IEEE Energy Conversion Congress and Exposition, 2011Several Maximum Power Point Tracking MPPT methods have been proposed looking for more efficient Photovoltaic (PV) system. Some of them are simple but imply low efficiency compared with more sophisticated method. The short-circuit current is a simple method to achieve the maximum power point based on the fact that the current at the maximum power point ...

External impedance vs. short-circuit currents
Electrical Engineering, 1934Effects of external impedance on short-circuit currents in synchronous machines and in networks are discussed in this article. The material presented is not claimed to be new; its chief value lies in the confirmation of calculations by test results, which tends to increase confidence in formulas previously developed.

Evaluation of Short Circuit Currents Effects on Power Transformers’ Residual Service Life
International Conference on Industrial Engineering, Applications and Manufacturing, 2019Power transformers’ residual service life is determined by the level of their windings insulation wear. Existing regulatory documents, dedicated to the evaluation of the insulation relative wear, consider the effect of currents continuous work loads and ...
