Calculating Max deviation in C

[ajit_nayak87]

I am trying to implement above equation mentioned in link. I am using pic16F1938 for coding.

https://zenatix.com/current-and-voltage-unbalance-causes-and-counter-measures/

Can someone help me or suggest me formula to calculate Max-deviation In c

All the variable declared as Unsigned int. In the mentioned example for unbalance current how to keep percentage limit.

If it's just C coding, you could place each sample in an array and create a function using 'for-loop'.

I have implimented code considering the example. But in the example it not mentioned in which 2 phase unbalance has occurred.
can someone guide me here.

unsigned int Max_Current=0;
unsigned int Min_Current=0;
unsigned int Unbalance_limit=10;
unsigned int Max_Deviation=0;
unsigned int Percentage_Unblance=0;



void Unbalance_Check()

{

Imean_Current=(Rph_Current+Yph_Current+Bph_Current)/3;

if((Rph_Current>Yph_Current)&&(Rph_Current>Bph_Current))
{
Max_Current=Rph_Current;

}else if((Yph_Current>Rph_Current)&&(Yph_Current>Bph_Current))
{
Max_Current=Yph_Current;

}else if((Bph_Current>Rph_Current)&&(Bph_Current>Yph_Current))
{
Max_Current=Bph_Current;

}else if((Yph_Current<Rph_Current)&&(Yph_Current<Bph_Current))
{
Min_Current=Yph_Current; 

}else if((Rph_Current<Yph_Current)&&(Rph_Current<Bph_Current))
{
Min_Current=Rph_Current; 
} 

else if((Bph_Current<Yph_Current)&&(Bph_Current<Rph_Current))
{
Min_Current=Bph_Current; 
}

Max_Deviation=Max_Current-Min_Current;

Percentage_Unblance=(int)((Max_Deviation/Imean_Current)*100);

if(Percentage_Unblance>Unbalance_limit)
{
CRUnblance_Flag=1;
}else
{
CRUnblance_Flag=0; 
}
