Claim:
1. A method of protecting one or more passive components connected to a high-frequency generator, the method comprising: generating a high-frequency power at a fundamental frequency using the high-frequency generator; transmitting the high-frequency power in a first direction to a load by a high-frequency cable; determining a variable related to a high-frequency load on at least a first passive component connected to the high-frequency generator by using at least one of the high-frequency power in the first direction or a reflected power in a second direction from the load, the reflected power being generated by the high-frequency power reflected by the load and comprising power at least at one frequency different from the fundamental frequency; comparing the determined variable with a reference variable which describes a maximum load on the at least first passive component; and adjusting the high-frequency power, generated by the high-frequency generator at the fundamental frequency, based on the comparison result.
