The electrosurgical system includes a multiplesecondary transformer (40) configured for sensing voltage. The multiple-secondary transformer (40) includes a primary winding (42) coupled to an active terminal and a return terminal (30,32) 10 of the electrosurgical system and a plurality of secondary windings (44,46). Each of the secondary windings (44,46) is configured to transform the radio frequency voltage into a sensed voltage. Each of the secondary windings (44,46) includes an output (50,52) coupled to a sensor circuit (22) and configured to transmit the sensed voltage to the sensor circuit (22).
