PROBLEM TO BE SOLVED: To provide a CT receiver which can reliably determine a direction of flow of a ground fault current while detecting the ground fault current during an accident point survey, so as to achieve improvement in workability in the accident point survey.SOLUTION: A CT receiver includes: a housing 10 including a hook part 10b for being hooked on a distribution line; a first CT sensor 20 and a second CT sensor 22 which are provided to the housing 10, which are arranged side by side along the distribution line when the housing 10 is hooked on the distribution line, and which detect a pulse-like ground fault current flowing through the distribution line; a first light emission part 30 and a second light emission part 32 arranged at the housing 10; and a light emission control section 50 for making the first light emission part 30 and the second light emission part 32 to emit light in different light emission manners when the first CT sensor 20 detects the ground fault current first and when the second CT sensor 22 detects the ground fault current first.SELECTED DRAWING: Figure 1 |
