Electrical Current Measurements Half Effect Current Transducers-Closed Loop
Closed loop Hall-effect current transducers use a secondary winding to null the effect of the primary turn. The feedback current is controlled to exactly cancel the flux created by a conductor passing through the window aperture. Specific performance characteristics of closed loop Hall-effect transducers include:
Use CTA800 for instrument power source and signal conditioning.
Typical Applications
The CTF and CTFB current sensors are highly precise and used extensively on ac, dc pulse and variable frequency drive applications. Used extensively in the wind turbine industry for more than 25 years.
