Current against slip relationship of induction machine?

AI Thread Summary
The current against slip relationship in an induction machine indicates that as slip increases, the current drawn from the line also increases. Slip is defined as the difference between the stator and rotor magnetic fields. A higher slip occurs when the motor is under heavy load, leading to increased current draw. If the load exceeds the motor's capacity, excessive slip can result in a current pull that trips an overload protection mechanism. Understanding this relationship is crucial for effective motor operation and protection.

Current against slip relationship of induction machine??

Please could someone explain to me the relationship between the current and the slip value of an induction machine. I have plotted a graph and I am wondering how to interpret this?

Thankyou.

If you are writing about an induction motor then the slip is the difference between the stator and rotor magnetic field. The larger the slip the greater the current pull from the line. When the motor is working there is always slip and if the load is too great for the motor the slip causes a higher than designed current pull and this trips an overload.
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
