Functional characteristics
1, the product is composed of KDZD300A cable outer sheath loop grounding test handheld host and special KDZD300A cable outer sheath loop current clamp.
2, suitable for measuring cable sheath circulation, cable sheath grounding current, harmonics, interharmonics, total harmonic rate, leakage current, frequency, waveform, etc., in substations and power plants. The 3.5-inch color LCD screen can display the size and waveform of the measured current in real time, and the Chinese graphical interface makes the operation intuitive.
3, special KDZD300A cable outer sheath circulation current clamp selection of special alloy, double layer magnetic shielding technology, the influence of external magnetic field is small, strong anti-interference ability to ensure year-round uninterrupted measurement of high precision, high stability, high reliability
4, non-contact measurement, no need to disconnect the line under test, safe and fast.
5, the whole machine adopts 32-bit high-speed DSP and FFT transformation, digital filtering and other technologies, anti-interference ability is strong, to ensure accurate and reliable data.
6, built-in large capacity lithium battery, can set automatic shutdown time and custom edit the sample number, easy to use in normal conditions can work for more than 8 hours.
7, the test program is simple and efficient, the instrument automatic measurement, waveform display.
8, the menu is simple and friendly, the display data chart is clear and easy to read, and can be clearly displayed in the sun.
9, the instrument with perpetual calendar, data storage up to 104 groups, shutdown without losing data.
