A method of performing an electrosurgical procedure includes activating an electrode of a surgical instrument by applying an output power signal with a first energy output profile from a generator to the electrode. An induced electrical parameter of a conductive component is monitored via one or more sensors, the induced electrical parameter being associated with a predetermined electrical parameter threshold. The induced electrical parameter includes a parasitic energy loss. When the induced electrical parameter measured from a conductive component of the surgical instrument meets or exceeds the predetermined electrical parameter threshold during the operation, the output power signal of the generator is adjusted from a first energy output profile to a second energy output profile. The adjustment is operable to reduce the induced electrical parameter measured from the conductive component of the surgical instrument; and to reduce the parasitic energy loss without ceasing delivery of energy to the electrode.
