Short Circuit Calculation Methods

چکیده
All electrical systems are susceptible to short circuits and the abnormal current levels they create. These currents can produce considerable thermal and mechanical stresses in electrical distribution equipment. Therefore, it's important to protect personnel and equipment by calculating short-circuit currents during system upgrade and design. Because these calculations are life-safety related, they're mandated by 110.9 of the NEC, which states:

A Comparison of Short Circuit Calculation Methods and Guidelines for Distribution Networks
The paper focuses on several different short-circuit calculation methods and standards/guidelines. Special attention is paid to modelling enhancements of a typical steady state short circuit calculation to take into account the impact of AC and DC decay. Several networks were used to test these enhancements and the findings are summarised on a representative section of a genuine distribution ne...
متن کامل3D Finite Element and Mixed Finite-Boundary Element Method for the Magnetic Field Analysis of Power Transformers
Power transformer analysis and design focusing on the equivalent circuit parameter evaluation by magnetic field numerical calculation is presented. Two kinds of numerical techniques are examined: the threedimensional (3D) finite element method (FEM), adopting a particular reduced scalar potential formulation and the 3D mixed finite element-boundary element (FEM-BEM) method. The methods are vali...
متن کاملAn Innovative Simple Test Circuit for Single-Phase Short Circuit Making Test of High-Voltage Switching Devices
Nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. Although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather d...
