Instructions for use of the voltage transducer model LV 100
Primary resistor R
1 : the transducer’
s optimum accuracy is obtained at the nominal primary current. As far as possible, R
1 should be
calculated so that the nominal voltage to be measured corresponds to a primary current of 10 mA .
Example: Voltage to be measured V
PN = 1000 V
a) R
1 = 100 k /40 W, IP = 10 mA
Accuracy = ± 0.7 % of V
PN (@ TA = +25°C)
b) R
1 = 400 k / 5 W, IP = 2.5 mA
Accuracy = ± 2.5 % of V
PN (@ TA = +25°C)
Operating range (recommended) : taking into account the resistance of the primary windings (which must remain low compared to R
1, in order
to keep thermal deviation as low as possible) and the isolation, this transducer is suitable for measuring nominal voltages from 100 to 2500 V.
