Magnetooptical current transformer. 3: Measurements.
A laboratory setup of a magnetooptical current transformer was established. A ingle-mode fiber acts as both a measuring sensor and a transmission line. The overall measurement accuracy at room temperature within a primary current range 50-1200 A is better than 0.24%, the SNR at 1000 A is 85 dB. Current measurements of high accuracy were also performed in the -20-+ 45 degrees C temperature range.
