Instructions for use of the voltage transducer model LV 200-AW/2
Primary resistor R : the transducer’s optimum accuracy is obtained at the nominal primary current. As far as possible, R should be

calculated so that the nominal voltage to be measured corresponds to a primary current of 20 mA .
Example: Voltage to be measured V = 1000 V

Operating range (recommended) : taking into account the resistance of the primary windings (which must remain low compared to R in order
1,
to keep thermal deviation as low as possible) and the isolation, this transducer is suitable for measuring nominal voltages from 100 to 2500 V.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
