Gas Insulated Substations | Electrical Substation ... Insulated Substations (G.I. S) Definition : A gas insulated substation (GIS) is a substation that uses a superior dielectric gas, sulfur hexafluoride (SF6), high-voltage. The basic principle of gas-insulated equipment : Is that the high-voltage current- carrying parts are within a metal enclosure and are held in a concentric configuration by cast epoxy spacer insulators.

HVDC converter stations HVDC Light semiconductor valves and converter reactors are placed inside, and DC and AC yards can be located in buildings on request. In a classical converter station, the semiconductor valves are housed in a large building; the small building is for the control and auxiliary systems.

Instrumentation in petrochemical industries - Wikipedia elements of instrumentation. Instrumentation includes sensing devices to measure process parameters such as pressure, temperature, liquid level, flow, velocity, composition, density, weight; and mechanical and electrical parameters such as vibration, position, power, current and voltage.. The measured value of a parameter can be displayed and recorded either locally and/or in a control room.

Overview of Smart Substations - ScienceDirect· The application of new equipment, such as electronic instrument transformers (EITs), MUs, and CBM IEDs, and the changes in the layout of IEDs in smart substations have brought new problems to the secondary equipment: the speed and reliability of relay protection reduce, and the failure rate of IEDs rises, which makes the maintenance and testing ...
