1. An electrosurgical system comprising:
an electrosurgical instrument including an electrode having a polymeric dielectric coating;
an electrosurgical generator configured to generate RF energy;
a sensor configured to sense at least one parameter of the RF energy; and
a controller configured to:
control the electrosurgical generator to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating;
determine whether the conductor breakthrough occurred based on at least one parameter of the RF energy; and
execute at least one of a treatment algorithm or output a regrasp alarm based on a determination of the conductor breakthrough.
