ABSTRACT:
An electric field detector which comprises means for generating a linearly polarized light, a polarizing element including a ) Pockels cell made from a Z-cutting quartz which transmits the polarized light toward a Z-direction and changes the phase difference of two light components of a crystal in response to the magnitude of the electric field strength. The electric field detector of the invention can be widely used in measuring conditions of an electrical machine.
