2. The Problem
• A 3 phase balanced ∆ connected load having
impedance of 3+4j per phase is connected to a
three phase balanced supply. Find VP , IP , IL ,
Power factor, Reactive power, Apparent power
and Active power. Line voltage is given as
input.

3. The Program
• #include<stdio.h>
• #include<conio.h>
• #include<math.h>
• void main()
• {
• float p,z=5,vl,vp,il,ip,preac,pac,papp;
• clrscr ( );
• printf("Enter the value of line voltage:");
• scanf("%f",&vl);
• vp=vl;
• ip=vp/z;
• il=(1.732*ip);
• p=0.61;
• papp=vp*ip;

4. The Program…..
• preac=1.732*vp*ip*0.8;
• pac=1.732*vp*ip*0.61;
• printf("nphase voltage is= %fV",vp);
• printf("nPhase current=%fA",ip);
• printf("nLine current=%fA",il);;
• printf("nPower factor=%f",p);
• printf("nApparent power=%fVA",papp);
• printf("nReactive power=%fVAR",preac);
• printf("nActive power=%fWatt",pac);
• getch();
