Information about current transformer

AI Thread Summary
The discussion revolves around the differences between live type and dead type current transformers (CTs). Live type CTs have enclosures at line potential, making them hazardous to touch, while dead type CTs are at Earth potential, posing less risk. The advantages of live type CTs include potentially smaller size and reduced material costs. Participants suggest that the same principles apply to CTs as to circuit breakers. Overall, the conversation emphasizes the importance of understanding these distinctions for safety and application in electrical systems.

hello friends...i am facing difficulties in understanding the difference between live type and deadtpe current transformer...and also the advantage of live type over dead type?

I'm not 100% sure about current transformers, but I know the difference between live and dead tank circuit breakers is that the enclosure that houses the windings (i.e. the "tank") is at line potential (i.e. live tank) and the other is at Earth potential. (i.e. dead tank)

I'm sure you could apply the same concept to the housing of CT's.

They say if you touch a live tank you'll be dead and vice versa, if you touch a dead tank you'll live.

tell me the advantage of live type over dead type
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
