Cables above 35kV are mainly single-core cables with metal sheath. Since the metal sheath of the single-core cable is hinged with the magnetic field line generated by the AC current in the core wire, the two ends of the single-core cable have a high induced voltage.
Product Features:-
● Real-time monitoring of the ground current of three phase cable sheath, the total ground current and the operating current of any phase main cable;
● Real-time monitoring of three-phase cable temperature;
● Real-time anti - theft monitoring of cable sheath grounding;
● Time interval can be set;
● Alarm parameters and whether corresponding monitoring parameters are allowed to generate alarm can be set;
● Set the maximum value, minimum value and average value in the preset period;
● Real-time monitoring of the ratio of maximum and minimum value of single-phase ground current within the statistical period, and alarm processing;
● Real-time monitoring of the ratio of ground current to load within the statistical period, and alarm processing;
