Short-circuit current calculations for DC systems

Proceedings of 1994 IEEE Industry Applications Society Annual Meeting, 1996
The aim of the paper is to describe the methods contained in the International Electrotechnical Commission (IEC) draft standard "Calculation of short-circuit currents in DC auxiliary installations in power plants and substations", and to test them using the dynamic computer simulation.

Short circuit current in tight and leaky epithelia

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1978
The effect of short circuit current on the unidirectional fluxes of ions transported across tight and leaky epithelia was investigated. It was found that short circuiting of the frog gastric mucosa (classified as a tight epithelium) caused a decease of the passive JClms and a significant increase of the net Cl- secretion. However, no significant change

Modeling of Current-Limiting Circuit Breakers for the Calculation of Short-Circuit Current

IEEE Transactions on Power Delivery, 2015
A current-limiting circuit breaker (CLCB) can quickly interrupt circuit faults and limit the short-circuit current. Modeling of a CLCB is important for the calculation of short-circuit current and arc flash energy. Based on the analysis of the arc voltage waveforms of CLCBs, a new arc model is derived.

Short-circuit currents and recovery voltages

Electrical Engineering, 1949
FIELD tests were made on a 7,200/12,470Y-volt multigrounded rural distribution system to check fault current calculations and to investigate transient recovery voltages experienced as a consequence of clearing fault currents. Tests were also made using a miniature circuit representation of a rural distribution system in order to investigate the effect ...

Calculation of short-circuit currents

2011
The current that flows through an element of a power system is a parameter that can be used to detect faults, given the large increase in current flow when a short-circuit occurs. For this reason, a review of the concepts and procedures for calculating fault currents will be made in this chapter, together with some calculations illustrating the methods

Effects of short-circuit currents

2005
Calculation methods for the thermal and electromagnetic effects of short-circuit currents are dealt with IEC 61660-2, which is applicable to short-circuit currents in d.c. auxiliary installations in power plants and substations and IEC 60865-1, related to three-phase a.c. systems.

Limitation of short-circuit currents

2005
The expansion of electrical power systems by new power stations and new lines (overhead transmission lines and cable circuits) results in an increase of short-circuit currents due to an increase in sources feeding the short-circuit and due to a reduction of system impedance. The improvement of existing installations and the replacement of equipment are

The short-circuited fluxgate output current

Journal of Physics E: Scientific Instruments, 1989
The alternative coupling of short-circuiting the secondary coil of a fluxgate sensor by connecting it to the inverting input of a current amplifier is shown to have significant advantages over the more conventional unloaded or second-harmonic tuned voltage coupling.
