European studies concerning transient recovery voltages (TRV) on two large HV networks are presented. The work was requested by CIGRE and carried out from a statistical point of view in order to draw some conclusions for circuit-breaker standardization. The main study was performed by means of transient network analyzers; a computer was also used in certain cases and for data tabulation. The methods used and results obtained are presented and some conclusions are drawn.
