Development of an Experimental Setup for Open Core Optical Current Transducers

Optical current transducers have clear advantages over conventional current trans-formers and can be used specially for high current measurement in high power laboratories. But proper construction of these devices is not straightforward since several factors influence the accuracy of these devices. To better understand the optical current transducer performance, experimental setups are of great importance. This paper focuses on the development of exper-imental setups for studying open core optical current transducer performances under AC and DC excitations. The first setup is a DC setup which uses a polarization analyzer. This design benefits from an optical table for adjustment. The second setup addresses a DC setup which uses an extra linear polarizer and a photodiode instead of the…
