In cases where a transition section is used to close couple SIMOVAC-AR controllers to Siemens type GM-SG-AR medium-voltage switchgear, the hot gases and burning particulates are directly exhausted into a common PRC for both SIMOVAC-AR controllers and GM-SG-AR switchgear, before being vented ...

1.1. MV Switchgear The MV switchgear installed in buildings is a line-up made of ten switchgear panels (Figure 2). Air is often employed as an insulating medium, giving room for more design and line-up flexibility. The main functions and features of an MV switchgear panel are to separate ...
finite element method; mechanical stress; medium voltage earthing switch; type test; energy efficiency design index1. Introduction The medium-voltage (MV) earthing switch for indoor use is normally a part of MV switchgear. All switching apparatus of the MV switchgear are subjected to type testing....
Meanwhile, the hardware structure of the acquisition board is simple; it consists of the amplifying circuit, programmed bias voltage circuit, filter circuit, and ADC driving circuit. The parameters can be modified to fit other measure requirements, reducing the cost of design. Without connecting the...
