Annotation: The article evaluates methods for the calculation of spurious (self) inductance based on the example of con-design of busbars in the power supply testing system used to load of automatic circuit breakers DC. Also, a simulation model of the power supply for the calculation of inductances is built, and comparative data on the results of calculations and simulations, confirming the accuracy of the used methods and the adequacy of the simulation model are provided.
