1. An electrosurgical system comprising:
an electrosurgical instrument arranged to grasp and fuse tissue using radio frequency (RF) energy; and
an electrosurgical generator connectable to the electrosurgical instrument and configured to supply the RF energy through the electrosurgical instrument, the generator comprising:
an RF amplifier arranged to supply the RF energy through the electrosurgical instrument in which voltage of the supplied RF energy is applied in a ramping fashion and subsequently held constant, wherein the voltage of the supplied RF energy is held constant at a predetermined voltage,
a controller arranged to monitor a phase angle of the supplied RF energy, the controller is configured to signal the RF amplifier to terminate the supply of the RF energy when the monitored phase angle is less than a predefined phase value, wherein the predefined phase value is less than zero degrees.
