Autech – TPV 333mV Integrator and Rogowski coil Kit

TPV integrator TPV is a Three phase DIN-RAIL 333mv Output, Rogowski coil integrator installation in distribution box, in a plastic 1 module DIN-RAIL enclosure. What does Integrator do? • Rogowski coil output is weak voltage mV signal, the TPV has ability to amplify and convert it to standard signal which can be connected to a meter. • Rogowski coil output is proportional to the frequency of the measured current, the signal equalisation ensures a linear response on a wide frequency range. TPV allows to use coils on different electrical network frequencies, keeping the same output level over the frequencies. • An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an active electronic circuit with negligible offset and a good linearity. Feature TPV can be combined with any model and size of RCA Rogowski coils. On request the input value can be customised according to the application. TPV combined with Rogowski coil is a very flexible system, suitable for high power load analysis, impulsive current monitoring, DC ripple measurement, etc. Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.
