Calculating Short Circuit Current Upgrade Your InternetThis post offers with an alternative technique for the short-circuit present computation so-called the MVA method. It can be also sufficiently precise for technical engineers in practice for basic estimation of fault levels at any point in an electric network. There are usually several methods for the calculation of short-circuit currents. These can become split into statistical and numeric-graphical methods. This method is well-known because of its simplicity and relatives accuracy. The technique comprises of the program of special figure that provide the worth of the a.c. The drawback of nomograms is their restricted use just for radial networks and the truth that the technique accuracy is certainly directly dependent on the precision of reading from the graphs drawn. The drawback of this technique is definitely it is definitely cumbersome if the system under analysis contains various voltage levels. It can be structured on a numerical changes of the ohmic method. The initial phase of calculation procedure is certainly to convert classic single-line diágram of the power network to an comparable MVA diagram. The following steps are usually based on the simpIification of an equivalent MVA diagram to one last value of MVA at the fault point (this represents shórt-circuit MVA at thé mistake stage). Calculating Short Circuit Current Trial Power SystemAllow us believe that the industrial power system is connected through the strength line V1 and supplied from the 22 kV external distribution system. For sake of simplicity, we think about only one synchronous generator, TG, and one synchronous electric motor, SM1 in the commercial power system. The task will be to find out the worth of preliminary symmetrical three-phase short-circuit present at 6.6 kV busbar. For components linked in collection the comparable value of preliminary symmetrical short-circuit strength is similar to the amount of inverted MVA values of elements. ![]() The MVA method is recognized to become simple, quick, and easy, and will be sufficiently precise for technicians in practice for basic appraisal of mistake amounts at any stage in an electrical network.
