AC/DC CURRENT TRANSDUCERS

SENECA I T201 Series

AC/DC CURRENT TRANSDUCERS – T201 SERIES

T201 Series AC/DC Current Transformers

The Transducers that use the measurement based on magnetic induction technology are long life devices thanks to the principle of measurement that avoids thermal drifts and which exploits the generation of an induced current on the transducer output, through the variation of a magnetic field. A direct use will be possible without any external shunts, even for pulsed currents.

When a magnetic field is applied perpendicularly to a conductor, a voltage is generated transversally to the direction of the current flow. The Hall Effect Current Transducers are used as alternative to shunt when dealing with high voltages and high galvanic isolation.
