An example is disclosed in Japanese Patent Laid-Open No. 55-29211 as a ground detector. The problem with the earth detector disclosed in JP-A-55-29211 is that the time and elevator position at the time of ground fault detection are not recorded. For example, in elevators used at sites where condensation occurs, the condensation that caused the ground fault is often recovered during the investigation of the ground fault location, and ground fault reproduction tests are not conducted accurately. Therefore, ground fault accidents due to the same cause reoccurred.
