Abstract
Optic sensors, forming a part of a fiber optic measuring system, are very attractive for use in the electric power industry. At KEMA a current sensor and a voltage sensor have been built for use in high-voltage measuring systems with data-registration by transient recorders. The voltage sensor consists of a Pockels cell situated near the test object connected to a light source and detectors in the control room by optical fibers. A crystal of bismuth-germaniumoxide was chosen as electro-optic material because of its superior characteristics in relation to unwanted optical effects. Different light sources and fibers were tested. The sensor was calibrated between -3 kV and +3 kV. The signal to noise ratio is in the order of 1000 for a wideband sensor (rise time 25 ns) and 25000 for a slow sensor (2 kHz bandwidth). Interference free measurements of HV breakdown demonstrate the capabilities of the optic voltage sensor. These sensors are now in use in research work on switchgear and in lightning tests.
