## Delta Winding Configuration

In a **delta (Δ)** configuration, every phase winding is connected in a loop, with line conductors connecting at the junctions between windings. This means that the line voltage is measured over the entire winding, whereas the phase voltage is measured for each individual **winding.**

In a delta-connected winding, the windings are arranged in a triangle pattern, with one end of each winding connected to one end of the other two.

## Key Parameters

- Line Voltage (V_L) is the voltage measured across any 2 line conductors.
**Phase**Voltage (V_Ph) is the voltage determined across a single delta winding.

## Converting Phase Voltage to Line Voltage

To convert phase voltage (Vph) to line voltage (Vline) in a delta connection, use the formula

**Vline = √3 × Vph**

This is because the line voltage is the phasor sum of the voltages across two series-connected phases.

## Converting Line Voltage to Phase Voltage

To convert line voltage (Vline) to phase voltage (Vph) in a delta connection, use:

**Vph = Vline / √3**

In a delta connection, the line voltage is divided by √3 and applied to each phase winding.

## Practical Example

Assume the delta-connected system has a phase voltage (Vph) of 230V.

To determine the line voltage (Vline), we use:

Vline = √3 x Vph

Vline = √3 x 230V

Vline = 398.4V

To calculate the phase voltage, use the formula Vph = Vline / √3. For example, if the line voltage is 400V, the phase voltage would be 230.9V.

To convert phase & line voltages in a delta connection, multiply the phase voltage by √3, or divide the line voltage by √3.
