Negative Sequence Current(LLF) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Negative Sequence Current = (-1)*Positive Sequence Current
I₂ = (-1)*I₁
This formula uses 2 Variables

Variables Used

Negative Sequence Current - (Measured in Ampere) - Negative Sequence Current consists of balanced three-phase current phasors which are exactly at 120 degrees apart rotating counterclockwise in ACB rotation.
Positive Sequence Current - (Measured in Ampere) - Positive Sequence Current consists of balanced three-phase voltage and current phasors which are exactly at 120 degrees apart rotating counterclockwise in ABC rotation.

STEP 1: Convert Input(s) to Base Unit

Positive Sequence Current: 2.001 Ampere --> 2.001 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I₂ = (-1)*I₁ --> (-1)*2.001

Evaluating ... ...

I₂ = -2.001

STEP 3: Convert Result to Output's Unit

-2.001 Ampere --> No Conversion Required

FINAL ANSWER

-2.001 Ampere <-- Negative Sequence Current

What are sequence currents?

The unbalanced current flows in the circuit during the earth fault is known as the zero-sequence current or the DC component of the fault current. The zero phase sequence means the magnitude of three phases has zero phase displacement.

How to Calculate Negative Sequence Current(LLF)?
