LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
Instructions for use of the voltage transducer model LV 25-P
Primary resistor
R
: 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.
a)
R
1
= 25 k
/
2.5 W,
I
P
= 10 mA
b)
R
1
= 50 k
/
1.25 W,
I
P
= 5 mA
Operating range (recommended) : taking into account the resistance of the primary windings (which must remain low compared to
R
in order
to keep thermal deviation as low as possible) and the isolation, this transducer is suitable for measuring nominal voltages from 10 to 500 V.
Example: Voltage to be measured
V

= 250 V
Accuracy = ± 0.8 % of
