Description

Technical Field

[0001] The utility model relates to the technical field of phase detection, in particular to a phase detection device. Background Art

[0002] A phase checker is an instrument used to check the phase of power equipment before closing the loop and energizing it. Existing phase checkers are one-phase-one-channel devices, using a one-to-one phase comparison test. Two probes are connected to the corresponding jacks of the two phases to be measured. One reference probe is fixed, and the other probe is moved to perform phase detection. Phase difference is determined by comparing them one by one. Test results are manually recorded one by one, and analysis is performed to determine whether the three phases are in phase. This results in low detection efficiency and is limited by the technical level of the tester, which can easily lead to erroneous conclusions. Utility Model Content
