deltas are not feeding any circuit but only closed loop. Power circuit is only YY

Since your JB is already explosion proof, the termination will be same as insafe area. Check the type of terminal block and apply the compatible terminal lug. Scotty is correct, you need not to connect terminal lug on single conductor.

I want to parallel two tranfrormers. Both 132/33KV YNyn0, 75MVA but their tertiary windings are different d11 and d1 respectively. Can somebody tell me if it is possible to parallel these. In my opinion since the power windings are having the same vector group, it must possible to connect these...

Is it current transducer or current transformer. If it is current transformer then it is called Ring Core current Transformer. I don't know about any such transducer.

Now the vendor has given us two options either go fo H/B which is very expensive or H/F. We are thinking to go for H/F. If it serves our purpose, why pay more.

Yes the rating applies to both rotor and stator and it is class H with temperature rise B.

Recently we are working on procurement of new Gas Turbine driven generator. One of the vendor has quoted insulation class H and temperature rise B while others have quoted F/B. We are currently using machines with F/B and donot have any prior experience of H/F. Please let me know if there are...

I need to select a motor for pump of absorbed power 145KW. Can somebody tell me what is the API standard for selecting the motor capacity. Is it 10% or 15% or 20% higher than the absorbed power.

I want to refurbish my motor feeder for 160 KW motor. Due to space limitation in the feeder, I want to use some smart type motor rated circiut breaker or motor starter. Can somebody tell me where can I find it for such a large motor.

I Want to install a repeater station for communication with walkie talkies at my plantsite. The coverage area is 50km in radius. Can somebody tell me what is the top of the line repeater station available in the market. Please also let me know what are the benefits of using a duplexer with...

The reason for replacing the fuses is their bolted ends which make their replacement very difficult. The breaker that I have selected has a thermal and instantaneous unit. The value of unit is 10 times the rated current. I want to know that with this value of shortcircuit current what nominal...

I want to replace fuses of my Motor Control Centre with motor rated Circuit Breakers. The current rating of installed fuses is 2.5 to 3 times the rating of the motor. What rating of the motor rated circuit breakers should I use, either equivalent to the rating of the motor or maintain the same...
