high purity control abb
high purity control abbThe realization of high efficiency solar cells with low process cost is currently the most important technical issue for the major solar cell manufacturers, including Elkem. To this end, Elkem developed the five step process for purifying the silicon produced, with ABB control solutions including System 800xA controlling Steps 1 and 3 of the process line.
High-speed rail Load Development
2018/7/19The first high speed rail system began operations in Japan in 1964, and is known as the Shinkansen, or "bullet train." Today, Japan has a network of nine high speed rail lines serving 22 of its major cities, stretching across its three main islands, with three more lines in development.
high voltage Leak detector Way
High voltage leak detection (HVLD) is one of the emerging technologies for inspecting package defects and tampering. HVLD operates by applying a high voltage potential to electrically conductive products inside non or semi conductive package materials.

sf6 Call the police ProcessThe AVO court process. An AVO application contains a notice to the defendant to come to court on a particular date and time. This is called a 'listing date'. Once the application for an AVO is made, it must be delivered to the defendant personally by a police officer. This is known as 'service'.
medium voltage sf6 Detector Situation
Reviews: 1Estimated Reading Time: 8 minsPublished: 2017/6/28Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section "leakage from SF6 – filled equipment" which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the SF6 in one circuit breaker escapes suddenly and it is again assumed that the switch room is sealed and that ventilation is inoperative. (see figure 1). In practice, attention would be drawn to an abnormal leak by underpressure detectors fitted to the CBs. These normally operate around 80% of normal filling pressure, and at this point in time, only 20% of the available SF6 would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of SF6 in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of SF6 from one CB would reach 17,5 ppmv. The concentration of SOF2in the switchroom at 20% relative pressure loss (commonly the alarm level) w...See more on electrical engineering portalSiemens develops SF6 free gas insulated medium voltage switchgear | Press | Company | Siemens press.siemens/global/en/pressrelease/siemens develops...Siemens develops SF6 free gas insulated medium voltage switchgear. At this year's Hannover Messe, Siemens will present another medium voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12. The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas.
