Gas-insulated Switchgear (GIS) Testing - OMICRON Switchgear (GIS) Testing. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas.

The increasing demand for HVDC technology requires the adaptation of gas insulated switchgear (GIS) or lines (GIL), which were originally developed for the AC grid. GIS are
Harmonics Created by AC Frequency Converters and ... program performs Fourier analysis for frequency converter input current based on entered engine, transformer and inverter data and calculates amplitudes of harmonic currents . Calculated harmonic currents are voltages induced by harmonic currents by passing over grid, transformer and inverter feeding unit impedances.
Service for gas-insulated switchgear (GIS) switchgear Hitachi ABB Power Grids pioneered high voltage gas-insulated switchgear in the mid-1960s. Thanks to robust design, high quality from the start and a sound service strategy-some of the earliest products are still functioning and keep on serving their intended purposes in different applications worldwide, day in and day out.
Sf6 Gas Recycling and Refilling Device for Sf6 Tes - SF6 ... to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

Switchboard Insulation materials, components, machining ... 61439 is the new standard for low-voltage (LV) switchgear and control gear assemblies. There is a 5 year transitional period between AS/NZS 3439 and AS/NZS 61439, which started after the new standard was introduced in May 2016. During this time, compliant boards can be built to either standard. We produced a short overview and checklist.
ABB to install solar based micro grid at Vadodara facility 2015 ABB exhibited the first multisource micro-grid pilot at its Automation and Power World event in New Delhi, India. Over a period of 3 days, 1,350 kg of CO2 was saved and enough electricity was generated to power approximately 12,000 rural households.
