China High Quality earth electrode test Factory – Substation Temperature Monitoring System – HV Hipot
General Information There are usually two ways to monitor the insulation condition of high voltage electrical equipment in substations: online monitoring and live (portable) online detection. The former one can obtain the characteristic parameters reflecting the abnormal insulation of the equipment at any time, which is convenient for automatic management. However, the investment is relatively large, the installation and construction are relatively troublesome, and regular maintenance is needed. For the latter, it has the advantages of low investment, highly targeted, easy to install, maintain and update. As long as the sampling unit is installed in the electrical equipment in advance, a regular detection can be done for electrical equipment in operation, and insulation flaw can be f... -
OEM Best Sf 6 Leak Detector Manufacturers – 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... -
