China High Quality Leak Detector Price Factories – GD8000C SF6 Gas Leak Online Monitoring System – HV Hipot
Product Description GD8000C quantitatively leak online monitoring system is mainly used in the 35KV SF6 switch room and 500KV, 220KV, 110KV GIS room in the substation to monitor the SF6 gas leakage in the SF6 combined electrical equipment room environment and the oxygen content in the air in real time. When SF6 gas leaks, the density of SF6 gas is more than 5 times that of air, which accumulates in the lower space and causes local oxygen deficiency, that may cause major accidents. The system uses multiple sets of new high-sensitivity imported SF6-O2 sensors and temperature and humidity sensors. When the indoor SF6 and O2 concentrations change slightly, the sensors can respond to these changes immediately, even if the SF6 concentration is 10ppmv can be effectively monitored. The conce... -
OEM Best earth electrode test Supplier – Online Monitoring System of Circulating Current on Cable Sheath GDCO-301 – HV Hipot
General Information 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. Therefore, appropriate grounding measures should be taken to keep the induced voltage within the safe voltage range (usually no more than 50V, but no more than 100V with safety measures). Usually, the metal sheath of short line single-core cable is grounded directly at one end and grounded through gap or protection resistor at the other end. The metal sheath of long line single – core cable is grounded by three – phase segmental cross – connection. No matter which kind of grounding me... -
