Unbalance Protection Testing and Unbalance protection Calculation by manual
Unbalance current cause by two
1.Zero sequence current
2.Negative sequence current

Formula for Zero sequence current
I0=(IL1+IL2+IL3)/3

Negative sequence current formula
I2=(IL1+𝑎^2IL2+aIL3)/3

testing for Negative sequence protection by using secondary injection kit. (46 protection testing )
