How much pole motor can be desion for 415 volt ,50 hz.Power supply. in pratical condition . Prakash veer singh
5 8270last week we did the REF relay test by closing single pole (R phase) of CB and apply 380V at the primary of delta transformer. we get 33A at the primary of the R phase star end. but we get 380A at both R an B in delta side. how and why?
1 3600a 3 phase slip ring induction motor is wound for 4 poles on stator and 6 poles on rotor; when 3 phase balanced voltage source at 50 hz is applied to motor it will run at a)1500rpm b)1000rpm c)750 rpm d)zero rpm
13 25504WHAT WILL BE THE SPEED OF MOTOR IF NO.OF POLES ON STATOR ARE NOT EQUAL TO NO. OF POLES ON ROTOR.???
4 7735Which is stiffer between salient pole rotor and cylindrical rotor synchronous machines? Justify your answer.
1 14487Which theory is used in the analysis of salient pole rotor synchronous machines? Who is credited for this developement? Could the same theory be used for cylindrical rotor synchronous machines?

hi,iam learning testing tools in mindq.i want to put 2+exp. is there any problem with that. tell me what are the Interview questions for experienced peopole. please give me the answer. thanq
I got some information from the QTP help.But i am not sure whether through this process will QTP work or not bellow is the Help what I have Remote setup Settings Remote WSH, which is a new technology included in WSH 5.6, provides the ability to run a script on a remote machine or machines. With Remote WSH, the script is physically copied from the local machine to the remote machine before executing. In order to enable Remote WSH functionality, you must first set up the remote machine with the proper security settings. The steps below perform the tasks that enable Remote WSH. Note Both the remote and local machines must be running Windows NT 4 SP3 or greater in order to use Remote WSH. To enable a machine to run remote scripts 1. Install WSH V5.6 on the machine. If you are using Windows 2001 or have installed Internet Explorer 6 or greater, WSH 5.6 has already been installed. Note WSH 5.6 is available for download from the web at http://msdn.microsoft.com/scripting 2. Add yourself to the remote machine's Local Administrators group. 3. To enable Remote WSH, use Poledit.exe on the server. Note An administrator who wants to enable Remote WSH must either acquire the Windows 2000 resource kit, or use http://msdn.microsoft.com/scripting to acquire the necessary windowsscript.adm file that contains the WSH settings. The windowsscript.adm file must be copied to the server that sets the gapplicabel group's policies. Although it is not necessary to copy the file to the server's \WINNT\INF directory, this is nonetheless where the default adm files are located. Note For more information on Poledit.exe, see the Poledit.exe's online help system. 4. WSH should now be enabled on the machine. To test it,. WSH 5.6 can run scripts that reside on remote systems. The following scripts demonstrate this capability. These scripts make the assumption that the files are located on a local machine directory called "c:\wsh5.6"; change the local path and the remote machine name as necessary. After initially running RemoteTest.WSF on the local machine, there may be a small pause as DCOM verifies your identity. After you see the "Done" message, a file named "c:\beenhere.txt" on the remote machine indicates the time that you executed the command (from the remote computer's clock). Script to run scripts remotely set oController = CreateObject("WSHController") set oProcess= oController.CreateScript("c:\wsh5.6\beenhere.wsf","remmachine") oProcess. Execute Could you tell me will it work fine

Dear sir How are you? i am jordanian female live in saudia arabia my student visa got refused 2 times my question is should i replay agian in jordan or saudia arabia my last time was 5 months ago and should i aplay for college or english institute? and should i take tofel test first do u think does the tofel help or doesnt matter please i need your help some pepole told me if i got refused once i will never get my visa is that right? thanks alot
There are 90 cows and 9 poles.you have to tie cows to pole such a way that each pole is tied with odd number of cows and no pole should be left empty?
Hi everyone. Some Generators uses 3-Pole breakers with extra contactors for Neutral. Some uses 4-Pole. Why so? What is the idea behind this? Thanks in advance for the solution. Kr.
I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
What are the components connected in between the power supply coming from an electric pole to HT & LT Panels in a large commercial building or how the power supply connected from Electric pole to Transformer & then to the HT & LT panels of a building?

Some time when i wanna learn the object i face issue like i am not able learn the object in proper manner... eg:for text bo on web page it should learn as webedit but some times it reads as winobject:internetexpoler-server, because of this i have to uninstall the qtp and re-install it again when i do this it reads the object perfectly.....plz suggest the soln
