The RCTi is a current transducer for permanent installation.
Simple to install and easy to retrofit, the Rogowski (sense) coil is thin, lightweight, flexible and clip-around.
The secondary output from the transducer is an instantaneous voltage proportional to the measured primary current providing an accurate, low cost, wide-band measurement of the primary current.
The RCTi is typically used with power and harmonic meters and analyzers, digital multi-meters, oscilloscopes, data-loggers and data acquisition cards.
