It adopts advanced arc reflection test technology, which can accurately identify high-resistance grounding faults, flashover faults and other fault types that are difficult to detect by traditional equipment. The 7-inch industrial LCD display supports real-time display of test waveforms and zooming to view details. The aluminum alloy shell with IP65 protection grade can adapt to extreme outdoor working conditions. It supports dual power supply modes of AC mains and backup lithium battery to ensure that operations will not be interrupted. It is equipped with an Ethernet interface to realize remote data synchronization, and can upload test data to the operation and maintenance management platform, adapting to the digital operation and maintenance needs of large-scale power grids.
The whole machine has dimensions of 450mm×320mm×200mm, with a net weight of 8.5kg. It adopts an aluminum alloy + ABS composite body, with an IP65 protection grade, and the working temperature range is -20℃ to +50℃. It supports three test modes: pulse voltage, low voltage pulse and arc reflection, the test voltage covers 0-30kV, the test range can reach 0-50km, and the measurement accuracy is ±1%. It is equipped with dual communication interfaces of Ethernet and USB, can store 5000 sets of test data, and supports external large-capacity mobile storage devices to expand storage space.
