Hangzhou High Voltage Technology Co., Ltd.  

Product Name: CT5250t Earth Network Grounding Parameter Comprehensive Test Vehicle Model NO.: CT5250T Trademark: HZHV Origin: Hangzhou, China Product Description The instrument uses a new variable frequency AC power supply and anti-interference technology of different frequencies, which can accurately measure in the strong interference environment of the substation.Functional features: 1.It can complete the ground impedance, ground resistance, ground reactance, field surface potential gradient, contact potential difference, contact voltage, step potential difference, step voltage, pole tower shunt, pole tower shunt vector, grounding stake (current pole, voltage Pole) resistance, soil resistivity and other grounding parameters measurement,2.Impedance measurement simultaneously displays the measured value and correction value of impedance, resistance component, reactance component.3.It can automatically calculate the diversion coefficient, the diversion vector and the actual dispersion vector of the ground network.4.All current measurements of the frequency selective multimeter are compatible with three methods: direct measurement, Rogowski coil (flexible current clamp) measurement and clamp-type current transformer measurement. The measurement method does not need to be set manually, and the system automatically recognizes and judges.5.The anti-interference ability is better than 1000 times the signal amplitude, and the amount of interference and the corresponding signal-to-noise ratio are displayed in real time.6.Configure thermal printer, support internal storage of measurement data and U disk storage.Composition:1.
