Featured Examples
AC Cable with Bonded Sheaths
A three-phase cable model comprised of multiple pi-sections. Each phase is enclosed in a conductive sheath. The conductive sheath is connected to ground at either end of the cable through a simple resistance. A high-voltage source provides power to an unbalanced resistive load through the power cable. You can configure the sheath to be either series-bonded or cross-bonded. You can also configure the number of pi-sections. Increasing the number of pi-sections improves the accuracy but slows down the simulation. To facilitate convergence, the voltage source includes an internal impedance.
Tap-Changing Transformer for Automatic Voltage Regulation
Use a single-phase tap-changing transformer to control the voltage across an RLC load. The system contains an AC voltage source that generates a 60 Hz sine wave (located on the left-hand side of the circuit). The root-mean-square value for the voltage generated by this source is 120 V (reference voltage).
Model Hysteresis and Eddy Current Losses in an Iron Core
Model the hysteresis and eddy current losses in the iron core of an electrical transformer using the Magnetic Core block. This block represents a magnetic core with magnetic hysteresis and implements the Jiles-Atherton model. You can parameterize the block using saturated B-H curve data, magnetic characteristics, or the Jiles-Atherton parameters.
Model Constant Power Consumption with Varying AC Voltage Supply
Model constant power consumption using the Constant Power Load block in an AC circuit with varying voltage controlled by a Tap-Changing Transformer block.
