    Overview of the Function 1.1 Introduction Introduction The Point-on-wave switching function in SIPROTEC 5 is used to reduce increased electrodynamic and dielec- tric loads, which are caused by non-optimal switching of circuit breakers in the network. In extreme cases, these loads reduce the reliability and life of the equipment installed in the network or lead to unnecessary opening operations by the protection device.

  • Page 13 Overview of the Function 1.3 Influencing Factors on Desired Closing and Opening Instants Closing a Grounded Capacitor Bank For each phase, the voltage across the contact gap of the circuit breaker is decisive for the selection of the correct closing instant.

The target instant is the voltage zero crossing in each phase, where a time offset of the three phases is required due to the phase displacement of their zero crossings.
