EN 50526-3:2012,6.5 The margin between the residual pressure and the rated impact voltage is generally considered. The rated impact voltage of 1.5kV system and OCS connection equipment is 10kV (EN 50124-1, OV3, Table D-1 and Table A-2). Impact voltage> K * residual voltage (K=1.25~1.4), that is, the residual voltage needs to be less than 7.14kV. |
