China High Quality earth tester model Supplier – 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...

China High Quality power transformers Suppliers – Partial Discharge Online Monitoring System of GIS – HV Hipot
General Information Gas-insulated metal-enclosed switches (GIS) and gas-insulated metal-enclosed transmission lines (GIL) are one of the most important devices in the power system. They have the dual tasks of control and protection. If they failed during operation and the problem cannot be solved timely,it will cause serious damage to the grid. Partial discharge fault is a common fault type of GIL/GIS. It is necessary to use GIS partial discharge online monitoring and fault location system to perform real-time online monitoring of GIL/GIS partial discharge signals and analyze and process the measured data and real time give comprehensive judgment of insulation status. Then repair schedule can be arranged according to the monitoring results to avoid major grid accidents caused by equi...
