Title:
PORTABLE EARTH LEAKAGE OPERATION TESTER
Document Type and Number:
Japanese Patent JP2017181119
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a portable earth leakage operation tester capable of reducing the time and labor required to input operating current information during a test, and meanwhile, obtaining lower-limit value information of an operation in a short time, and outputting test result information to the outside.SOLUTION: A portable earth leakage operation tester comprises: operating current information input means 111 for inputting operating current information in an apparatus 10 to be tested interposed in a cable run; output current value determination means 12 for calculating and determining the current value output on the basis of the input operating current information; current output means 13 for outputting the determined output current value to the cable run; operating state detection means for detecting an operating state of the apparatus to be measured; operating state discrimination means 122 for discriminating whether the apparatus to be measured operated when the detected operating state data is input; operating time measurement means 123 for measuring lapse time lasting from start of output of the output current value to end of the discrimination; and output means 150 for outputting the operating current information and information indicating whether the apparatus to be measured performed earth leakage operation to the outside of the tester.SELECTED DRAWING: Figure 1
