SCR Propulsion Systems: Electric Motor & Towboat Power

AI Thread Summary
SCR refers to silicon-controlled rectifiers, which are used in electronic circuits for protection but are not directly related to powering towboats. The discussion centers on whether an electric motor can effectively power a towboat using batteries and a backup generator to achieve 1800 hp. It is noted that mechanical output from the generator must first reach 1800 hp to generate equivalent electrical power, making direct mechanical drive a more straightforward option. The feasibility of using electric propulsion in towboats remains uncertain without further clarification on SCR's intended meaning in this context. Overall, the conversation highlights the complexities of integrating electric motors into traditional towboat systems.

Anybody know anything about SCR...can an electric motor power a towboat with batteries and back up generator power say 1800 hp.

I have no idea what is "scr."

Why not just use the mechanical output of the generator directly to drive the boat. You won't get 1800 hp of electrical power out of the generator unless you could already get at least 1800 hp of mechanical power.
 
The only "SCR" I know is a silicon-controlled rectifier -- basically a normally-closed switch that is opened at a theshold voltage and cannot be closed again until the current through it stops. They're commonly used for protection circuits on ICs -- if you oversupply the part, the SCR opens and conducts large currents, protecting the more sensitive circuitry for a while (until the heat dissipation blows the chip up anyway).

I don't think this is what djreidt means, though..

Thread 'What happens if shielded cable has 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...
