We know that different types of components are used at the substation for transmission and distribution of electric power from the manufacturing plant. Below is a list of some of them.
- ACR (Automatic Re-closer)
- PT (Potential Transformer)
- CT (Current Transformer)
- VCB (Vacuum Circuit Breaker)
- Lightning Arrester
- PFI (Power Factor Improvement)
We have discussed in detail in the previous article about busbar. To read the text, enter the text in the busbar below.
ACR (Automatic Re-Closer)
Autoreclosure is a special type of circuit breaker in electrical distribution systems. When a fault occurs in the system, it opens the entire circuit and closes the circuit again after a certain amount of time (within seconds/time is set). If the system has faults repeatedly, the recloser will open the system repeatedly and close shortly afterward. There will be auto reclosure at the substation.
When the system faults, an engineer can set how many times the recloser will open and close the circuit.
Examples: Suppose there is a fault in the system, open the recloser circuit and close it again after some time. But the breaker realized that the fault was still there and he opened the circuit again and after some time closed it again. An engineer can set how often this will happen. If there is no fault then the recloser will open the circuit. If only the circuit breaker was used in this case, the circuit breaker would open the circuit immediately after getting fault but could not be closed automatically again.

PT (Potential Transformer)
We have discussed in detail about the Potential Transformer in a previous article. Enter the Potential Transformer text below to read the text.
CT (Current Transformer)
We have discussed in detail the current transformer in the previous article. To read the text, enter the current transformer text below.
VCB (Vacuum Circuit Breaker)
A vacuum circuit breaker is a circuit breaker that completes the braking process by putting a fire through the vacuum. This circuit breaker is in the case of medium voltage ie 11 From 33 Used in KV.
Vacuum circuit breakers are used for:
- Just like the packet, it looks reliable and very durable.
- There is no risk of fire here.
- There is no chance of any gas being produced before or after the breaker operation.
- It can break any fault current.
- It does not require much maintenance.
We have discussed in detail about the transformer in the previous article. To read the text, enter the transformer text below.
The insulator is usually located between the conductor and the support and connects the two. There is no current flowing through the insulator, thus the current cannot be transmitted from the transmission line to the current pile.
Of Lightning Arrest
The word lightning means lightning and Arrester means arrest. That is, if there is a thunderstorm on the transmission line, then there is a possibility of getting too much voltage into the line, causing a lot of damage. For this reason, using the lightning array, the excess voltage is discharged to the ground.
