Features
(1) 12-inch industrial-grade computer control, touch operation mode;
(2) Windows operating system, visual wireless expert guidance, 4G network;
(3)With functions such as distance measurement and speed measurement;
(4)400MHz sampling frequency, minimum resolution 0.5m (100m/us)
(5)Fully automatic continuous sampling, never miss any discharge waveform;
(6)Test method: multiple pulse sampling, induction sampling, flashover sampling, low-voltage pulse sampling
(7)The reflected signal sent by the pulse coupler is automatically displayed, and the full-length waveform of the open circuit of the cable is displayed at the same time. This makes the representation of the fault characteristic waveform extremely simple.
(8)With the function of storing massive test waveforms: The waveforms tested on site can be conveniently stored in the instrument in a prescribed order for recall and observation at any time.
(9)The measured fault point waveform and the good-phase full-length open-circuit waveform can be displayed on the screen at the same time for comparison on the same screen and superimposed comparison. Makes the judgment of the fault distance more accurate.
(10)Built-in polymer lithium battery power supply: it can work continuously for more than 4 hours after being fully charged. Fully meet the requirements of on-site testing. It can also work with an external AC power supply.
(11)Eight pulse transmission and fault reflection signals are automatically displayed, and the full-length waveform of the cable open circuit is displayed at the same time. This makes the representation of the fault characteristic waveform extremely simple.
