IPC: A61B5/055
Filed: 1989-09-22
Abstract: PURPOSE:To uniformize a sensitivity distribution by arranging a high frequency receiving coil to comprise three coils disposed perpendicular to one another so that information established is obtained simultaneously from each thereof. CONSTITUTION:Solenoid type coils 3 are combined above orthogonal surface coils 2a and 2b in such a manner as to compensate a low sensitivity part 33. In such arrangement, the three coils have sensitivity at about 90 deg. to one another to be orthogonal so that independent signals can be detected simultaneously from the three coils. Then, outputs of surface coils 2a and 2b are connected to input terminals (a) and (b) of a receiving circuit 23 and when outputs of the coils 3 are connected to an input terminal (c), output levels of the surface coils 2a and 2b give almost equal values. As a phase difference becomes about 90 deg.. A phase shifter 30a is set to 0 deg. and the one 30b is set to about +90 deg. or about -90 deg.. An attenuators 31a and 31b are both set to -0dB. In contrast, the outputs of the coils 3 are adjusted to such a phase correction value as to make an image pickup part the best according thereto automatically or manually. Attenuation value of the attenuator 31c is adjusted to meet optimum adjusting conditions according to a sensitivity difference between the coils 3. This enables a higher sensitivity with the uniformization of a sensitivity distribution of the orthogonal coils.

Abstract: PROBLEM TO BE SOLVED: To make correctly locatable a fault point even when an impedance of a transmission line is imbalanced by obtaining for every terminal of the transmission line the differential current of a fault phase corrected with the line impedance. SOLUTION: For example, the fault locator 1 at a two-terminal, parallel two-line transmission line has a CPU for operating, locating fault points, and the like. When a fault-detecting part 16 detects a fault such as a ground fault, a shortcircuit or the like, the CPU detects a fault phase and calculates an absolute value of a corrected differential current at the fault phase according to a predetermined method using a self impedance matrix (3×3) per unit length of a 1L and a 2L lines or a mutual impedance matrix (3×3) per unit length between the lines on the basis of sample values of a current, a voltage immediately before the fault which are stored in a memory 15. A distance to the fault point from each terminal is located with use of the calculation result. Fault points at a three-terminal, parallel two-line transmission line can be located by using the same apparatus.
