I got the Cadance OrCAD demo disc, but my files have the .SCH extesion and OrCAD is having trouble opening them and tells me to veiw Session Log, but i can not find any such file. any idea what's going on.
Does anyone have a suggestion on an elegant solution for limiting the inrush current going through a diode pack that is rectifying a 45V 150A current. The caps are very big and the initial draw is forcing me to rate the diodes at much higher than the nominal draw. If I can somehow limit the...
Does anyone know of a free Orcad viewer I can download? I want to view and perhaps print Orcad schematic drawings without having to purchase the whole software.
Thanks.
Some of my friends tell me the same thing "seek professional help", but I think they mean something totally different. The bottom line is that not many people are born as experts. We learn as we live and asking questions and being open to the advice of those with experience makes this learning...
Those were good suggestions. Our device is quite large, has a huge step down transformer, a PLC along with sensors and actuators. I think I want to take the path of jumpering the relays and the contactor. This opens up another area: design for testability. I can picture a set of terminals...
The article is by the people whose test equipment we are using. could you clarify what I am misreading? I am just curious how a professional test agency would tackle this problem. I agree that the Hipot test is mostly used for small appliances, but CE cert agency we are dealing with is asking...
I wonder if I am missing something. Unless I supply voltage to the DUT, the majority of my system will be isolated because of the contactor and the many relays. Are you suggesting each of these subsystems to be tested individually? I am reading the article bellow, last page...
The DUT is quite complicated and it has a lot of relays inside that cannot be mechanically activated, so we have to actually supply power to it to create a complete path.
Hi everyone,
I am new at this, so please forgive any ignorance that comes through.
I am tasked to setup a test procedure to conduct dielectric withstand test on a 480v 3phase system. Because of all the internal contactors and solid state relays, the DUT has to be powered up. In the...
