摘要： A welding system (116) monitors the changes in the power output provided from a power supply (12) to a device (310) to determine the inductance of power cables (24) between the power supply (12) and the device (310). The device (310) may determine the inductance of the power cables (24) based at least in part on a delay in a threshold change in voltage to the device after a change in the current demand of the device, a delay in the initialization of the change in the current demand of the device after an initialization signal, a rate of change of the current drawn by the device, or a relative comparison of the voltage to the device and the current drawn by the device, or any combination thereof. If the inductance of the power cables is greater than a threshold inductance, the device may signal the user, disable operation of the device, or any combination thereof.
