2016/12/4The circuit switcher is not equipped with a low pressure blocking scheme. This suggests that the interrupter would have operated even if there were loss of SF6 pressure. Interrupting under reduced SF6 pressure leads to an increase in the arcing time which in turn results in higher chopping currents when de energizing shunt reactors.
