Measurement of the output power of electrosurgical high-frequency equipment when simulating single fault conditions

Abstract

The issues of determining the output power of high-frequency electrosurgical equipment by simulation of single fault conditions in accordance with the particular standard DSTU EN 60601-2-2:2015 are considered. It is noted that modern high-frequency equipment is equipped with measuring units to control output current and voltage in order to ensure control of output power. A method for monitoring the performance of built-in protection systems of modern HF equipment is proposed if the output power exceeds the limits of allowable values under single fault conditions. This method is common for most operating modes of HF equipment. Practical examples of such tests are given.
