If a motor is not having name plate details how we can find out its rated speed.Is there any method to find the speed.

Could dark matter be an effect of massive amounts of matter moving thru the energy that permeates space, similar to voltage being induced in a moving conductor by a magnetic field? Matter warps space time, much as a conductor warps magnetic lines.It must require force of some type to move thru spac

hi friends,

WHAT IS THE IDEAL TIME FOR CATCH OF SIGNAL AT ANNOUNCER ?

11 ms is good ?

I want to see the transmit and return signals that the meter is generating, but I am having trouble finding an output that would give me the amplified return signal. Are there any outputs available on the basic meter that would let me see the amplified return signal?

1CX 300 sq.mm unarmored Cable using PVC Gland .It was terminated in the LV panel.Now the client was not accepting because,the reason is the gland plate was mild steel,so the cable entry area the magnetic path form so that to refuse. Now all the cable was terminated its very difficult to remove

what are your opinions about that reclosing at 420 kV lines with shunt reactors?

is it recommended way to put into practice?

We have 5 AC410 from ABB and one OS. One is the central plc and the other four are process PLCs distributed to different processes. We had a problem with the central PLC where by some one put some force on it's analog module by pushing it hard into the slot,the com card CS513 went off and non of t

hi all,

what do you think about ISA drts-6 ?

is there someone know that imperfect ways of ISA?

thanks for ur answers...

We have a SCADA system with 8 ABB AC410, 5 AC110, 2 AC70,a report station and two operator stations.

One of the AC410 is about 200m away from control room, 6 of AC41O are distributed to different process with 5 of them having additional AC110 (AVR COMPUTERS). 2 have additional AC70. One
