AI Thread Summary
Icw, Icm, Icu, and Ics are critical specifications related to the performance and protection capabilities of ABB Tmax circuit breakers. Icw refers to the rated current for continuous operation, while Icm indicates the short-circuit current rating. Icu is the ultimate short-circuit breaking capacity, and Ics represents the service short-circuit breaking capacity. Understanding these terms is essential for selecting the appropriate circuit breaker for specific applications, as terminology may vary by region. For detailed definitions and specifications, consulting the ABB catalog or relevant datasheets is recommended.

Can you explain to me what the meaning of Icw, Icm 'Icu, Ics,

We might assume these are currents, beyond that we will have no idea without more info...are you reading these on a datasheet, homework, schematic ?
 
It appears in the catalogs of electronic protection of the brekers ABB
 
Is it on line... can we have a link? ( Different countries and regions have different terminology - especially when referring to electrical protection)
 

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...
