Abstract
The current generation of offshore wind farms connect to existing distribution systems onshore. The concern with wind farm connections is the substantial submarine cable system, which results in a large net capacitive charge particularly under low export conditions. It is therefore important for the Distribution Network Operators (DNOs) to ensure that the circuit breakers installed at and near the point of common coupling (PCC) to the DNO’s network are fit for purpose with respect to switching operations and fault clearance
duty. This paper summarizes the results of transient recovery voltage (TRV) studies carried out to assess the capability of 132kV circuit breakers at the PCC and at neighbouring DNO system locations. The results are compared against the reference TRVs specified in IEC.

breakers are fit for purpose
