<p>PROBLEM TO BE SOLVED: To obtain a high quality optical voltage-current detector which is not removed by heat or external impact and protected against intrusion of rain. SOLUTION: The optical voltage-current detector for distribution line comprises a capacitor voltage divider 2 of semicircular cross-section having a notch disposed along a distribution line 1, an optical voltage sensor 3 for detecting the voltage of capacitor voltage divider 2, a field converging core 4 surrounding the distribution line 1, an optical current sensor 5 disposed at the gap in order to detect a current induced by the flux generated from the field converging core 4, and a tubular split case 6 surrounding the capacitor voltage divider 2 and field converging core 4. The case 6 is provided with counterbores 64A, 64B for supporting the capacitor voltage divider 2 at the opposite ends thereof, engaging parts 65A, 65B for clamping the capacitor voltage divider 2 at the opposite ends in the axial direction thereof together with the counterbores 64A, 64B, a counterbore 66 for supporting the field converging core 4, and engaging parts 67A, 67B for clamping the field converging core 4 together with the counterbores 66.</p> |
