Question
a) (i)Draw the schematic diagram of the
Potential Transformer and label the parts.
Also mention the range of meter used.
(ii) What are the advantages of an
Instrument transformer? (any four)
b) The output of a LVDT is connected to 11 V
voltmeter through an amplifier of
amplification factor 470. The voltmeter scale
has 168 divisions and the scale can be read
to 1/4th of a division. An output of 6.6 mV
appears across the terminals of the LVDT
when the core is displaced through a
distance of 3 cm. Calculate
(a) the sensitivity of the LVDT,
(b) sensitivity of the whole setup and
(c) the resolution of the instrument in cm
the sensitivity of the LVDT
the sensitivity of the whole setup
Resolution in cm
