This menu contains the supported nonlinear resistors and inductors. All the objects except the TACS controlled resistor can also have a nonlinear characteristic. These attributes can be specified by selecting the Characteristic tab of the Component dialog as shown in Fig. 4.57. The nonlinear characteristic of objects can be entered as piecewise linear interpolation. The number of data points allowed to enter on the current/voltage, current/flux or time/resistance characteristics are specified in the Help file of objects. U/I characteristics of nonlinear resistances are assumed symmetrical, thus (0, 0) point should not be entered. If the saturation curve of a nonlinear inductor is symmetrical start with point (0, 0) and skip the negative points. The hysteresis loop of Type-96 reactors is assumed symmetrical, so only the lower loop of the hysteresis must be entered. The last point should be where the upper and lower curves meet in the first quadrant. If you specify a metal oxide arrester with MOV Type-92 component, ATPDraw accepts the current/voltage characteristic and performs an exponential fitting in the log-log domain to produce the required ATP data format. |
