SYSTEM AND METHOD FOR DETERMINING INDUCTANCE OF A POWER CABLE

摘要

A welding system monitors the changes in the power output provided from a power supply to a device to determine the inductance of power cables between the power supply and the device. The device may determine the inductance of the power cables 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

1. A welding system comprising:
a welding-related device configured to be coupled to a power supply via power cables, wherein the welding-related device is configured to receive power from the power supply via the power cables, and the welding-related device comprises sensing circuitry configured to determine a parameter indicative of a delay between when the power is output from the power supply and when the power is received by the welding-related device through the power cables.
