1 phase and 3 phase electrical system. maybe my friend asked what is the electrical system 1 phase and 3 phase? What are the advantages of 1 phase and 3 phase electrical system?
or maybe you pay attention to the cable on the power pole and buddy think why use 3 pieces of cable like picture?
The following article will discuss about electrical systems of delta relation and electrical relationships of the stars every bit well as circuit images
understanding of electrical system 1 phase and 3 phase
3 phase electric system (phase) is an electrical system where in the process of energy delivery using 3 pieces of cable
This is different from the 1 phase electricity that often my friend uses in the home
The 3 phase system is more economical in electric power delivery, compared to a 1 phase system because of the same conductive size 3-phase electric system can conduct larger electrical power
3 phase electric is AC power (alternating current) which is sourced from 3 phase generator which use 3 same voltage conductor but differ in phase angle equal to 120 ° so that each current coming out of generator is different phase of 120 °
read also the understanding of AC and DC currents
In 3 phase electrical installation is experienced by 2 kinds of relationship that is a relation of delta (Δ) and star relation (Y)
The 3 phase system in Indonesia is also known as RST where RST is the name of the cable connector
The delta system uses 3 pieces of line while the star relationship uses 4 pieces of cable where the cable to 4 is a neutral cable (N) Which is the confluence of the three ends of the cable?
1 phase and 3 phase electrical system
3 phase power schemes for delta and star relationships are somewhat different
electric delta connection
The electrical scheme of the delta relation is usually used for high-voltage electricity of about 20KV or 20000V
Delta relationships use 3 pieces of line where the ends of the wires are connected to each other with a 120 ° angle difference. See picture at top
as for the schematic of the delta relation is as follows
electric star connection
In the electrical relation of the star the potential divergence between the ends of R, S, and T is 380V whereas the potential difference of the three ends of both R, S, T with neutral (N) cable is 220V
The relationship between the points R, S, T with the point N called 1 phase, this electricity is then circulated to homes with voltage 220VAC
In the electrical image of the star relationship above the possible difference between R-S, S-T, and T-R = 380V. electricity is called 3 phase
While the likely difference between R-N, S-N, and T-N is 220V. Electricity is called 1 phase and distributed in homes
So the article about 1 phase and 3 phase electrical system. To add insight, please read as well the difference between CT and Non CT transformer
