SF6 insulated load switch CHANGGAO

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their …Gas density monitors - Product overview - WIKA

M-Series STATCOM, a Voltage source converter (VSC) based modern compensation system, can act as a source or sink for reactive power. It consists of a controllable part that can operate as capacitive and inductive power and keeps the reactive power flow constant in the system.People also askWhat is a STATCOM reactor?What is a STATCOM reactor?A STATCOM is a voltage source converter (VSC) based device, with the voltage source behind a reactor. The voltage source is created from a DC capacitor and therefore a STATCOM has very little active power capability. However, its active power capability can be increased if a suitable energy storage device is connected across the DC capacitor.STATCOM – Working Principle, Design and Application ...
