Hall Effect Voltage Sensors / Voltage
Switches
Hall Voltage sensors
are based on Hall Effect and magnetic compensation principle. These
Voltage sensors can be used for measuring DC and AC voltages with different
wave forms. They have high electric isolation, high reliability,
good overload capability, small sizes and can be applied to switched
mode power supplies, UPS, overvoltage protection, electric power
network monitoring, AC frequency conversion servo-motors, etc.

Hall Effect Voltage
Transducers - Operation principle
-
A very small current limited by a
series resistor is taken from the voltage to be measured and is
driven through the primary coil.
-
The magnetic flux created by the
primary current IP is balanced by a complementary flux produced
by driving a current through the secondary windings.
-
A hall device and associated
electronic circuit are used to generate the secondary
(compensating) current that is an exact representation of the
primary voltage.
-
The primary resistor (R1) can be
incorporated or not in the Voltage transducer.
