Need laptop recommendations
Published (2009-11-07 18:27:00)
You will notice a huge difference between 2001+ and 2010 in both appearance and computer resource requirements. You may also have some "sticker shock" regarding the upgrade cost. Laptop specs depends on how full your wallet is. Skip Vista and go direct to Win7. Whether you need a 64 bit system depends on your models and assys complexity and size. However, a similarly spec's x64 system will cost as much as an x32 system, but...

Buying a new CMM system
Published (2009-11-07 16:08:00)
If you have time I would attend some of the shows or exhibitions like Westec early next year. i believe that the best way to evaluate a CMM is up close and personal just like buying used equipment as you are the only one that knows the application. Make sure if you purchase a refurbished one that the machine was returned to OEM specifications including any up grades that may have been missed. Here is a...

Soft start motor starts in 1 hour
Published (2009-11-07 13:27:00)
( When you start the motor you put a large amount of energy into the rotor as slip losses while the motor accelerates. You should include this when evaluating the apparent savings you will make. Your control gear will be a maintenance nightmare, figure on either putting in a grossly oversized contactor or replacing it fairly frequently. Your proposal is frankly a terrible one from the electrical point of view. A motor running a pump dumping...

( Generally when someone goes to the bother and expense to put in a standby/backup motor this signals an exceptional need for high reliability. As such you should not consider using one VFD for both motors. A VFD has about the same chance of failure as the motor it runs. The correct setup would be two VFDs and some logic to run both motors alternately. This prevents bearing failure from non...

I am guessing both gererators are rated at 120MVA. If you use a three winding transformer and it fails then you loose 240MVA of capacity. If you use two 2-winding transformers and one fails you only loose 120MVA of capacity. But the additional cost for two transformers includes an additional high side breaker, and relay control scheme.

Hi MIke. Sorry, I don't undertand your Q. Could you please provide more information. Actually, operation procedures are depend on primary configuration of SS and not on the voltage level. single bus for 35kV and 350kV, are same rules for switching. Best Regards. Slava

The IEEE C62 series covers surge arresters. Was your question about surge arrester or surge capacitor test standards? Your title says one thing, your post another.

or put the control valve down stream of the slug catcher. If the level is to high, pinch the flow out. This is better because upstream the shreading of the water/oil through the valve causes an emulsion.

( I recall a positive- drive infinitely variable bicycle transmission, announced maybe 20 years ago in the mechanical fish wrappers. I think it used radially sliding teeth on the crank sprocket, and a regular chain and hub. I don't recall ever seeing one in person. If you want us to download and read something, at least do us the courtesy of providng a link. , )

Can you take your corrosion products to an SEM and have them analysed (EDS)? That may reveal more info on the corrosion process.

Horizontal shear in a beam or plate girder is mobilized by bending, so horizontal shear is not 0 at the center as would be for vertical shear. It is actually at a maximum with the maximum moment. The shear is created by the tension/compression differential in bending.

Seems to me like they are using the economy's poor condition to take advantage of their workers. You should not have to go insane working 60 hour weeks just to ensure that you have a job in the future.
