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

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.

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.

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

Factors for the calculation of short-circuit currents

2005
Several factors for the calculation of short-circuit (s.-c.) currents have been introduced in previous sections, the origin of which will be explained within this section. · Voltage factor cmax and cmin for different voltage levels as per Table 4.1. · Correction factor using the %/MVA or the p.u.-system as mentioned in Chapter 2. · Impedance correction
