Line voltage (line-to-line voltage) in a system is the voltage between two given phases. The other hand, Phase voltage is the voltage between the given phase and neutral, (neutral is available in star connection but not delta connection).

Let me clear your confusions

IN Y CONNECTION:

1) line voltage =root3 * phase voltage

2) line current = phase current

IN DELTA CONNECTION:

1) line voltage = phase voltage

2) line current = root 3 * phase current
(3)

@Mahantesh.

Line voltage is the voltage which is between two phases and the current flows through those phases is known as line current.

I hope you understand.

In yy system hv each line current and phase current are equal.

What is the difference between line voltage and line current?

Ankita said:   1 decade ago
In Y connection line current=line voltage.
