So R1 should be calculated so that the rated voltage to be measured corresponds to a primary current of 10mA.For example: Measuring rated voltage VPN=250V:R1=25K/2.5W,IP=10mA Accuracy=±0.5% of VPN; b) R1=50K/1.25W,IP=05mA Accuracy=±1.0% of VPN; Operating range(recommended):taking into the resistance of the primary windings(which must remain low compared to R1.in order to keep thermal deviation as low as possible) and the isolation,the sensor is suitable for measuring nominal voltage from 10 to 500V.
