What is the line voltage of the three-phase network?

The Symmetrical Load Below Is Connected To A Three-phase Network. A Line Current Of 25A Has Been Measured.

Answers

Answer 1

Answer:

The line voltage of the three phase network is 346.41 V

Explanation:

Star Connected Load

Resistance, R₁ = R₂ = R₃ = 18 Ω

For a star connected load, the line current = the phase current, that is we have

[tex]I_L = 25 \, A = I_{Ph}[/tex]

Whereby the the voltage across each resistance = [tex]V_R[/tex] is given by the relation;

[tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R

Hence;

[tex]V_{Ph}[/tex] = [tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R  = 25 × 8 = 200 V

Therefore we have;

The line voltage, [tex]V_{L}[/tex] = √3 × [tex]V_{Ph}[/tex] = √3 × 200 = 346.41 V.

Hence, the line voltage of the three phase network = 346.41 V.

What’s a pigtail when wiring

Answers

Answer:

A pigtail when wiring is technique that is used in connecting a lot of wires together.

Explanation:

A pigtail is a wire that is short in length. It has two ends. One end has a connector while the other end has other wires connected to it.

Pigtail when wiring is the connection of more than one wire in a circuit to another device. Pigtail when wiring helps to extend the length of the wire in a circuit if the wire used it short).

Pigtail when wiring is a technique what helps to keep the circuit organised because it prevents the wires from getting tangled.
