1 RANGKAIAN LISTRIK 2 SINUSOIDAL STEADY STATE SINGLE &THREE PHASE CIRCUIT STAR-DELTA CONNECTION FREKWENSI COMPLEX LAPLACE TRANSFER FUNCTION TRANSFORMER TWO PORT NETWORK Ir. I.A.DWI GIRIANTARI,MEngSc.,PhD. SELASA, DH 102, WITA

2 KONTRAK KULIAH MIDDLE TEST/UTS = 35% ASSIGMENT/TUGAS = 15% PARTICIPATIONS = 10% FINAL EXAM/UAS = 40% TOTAL = 100%

3 INTRODUCTORY ALTERNATING CURRENT PEMBANGKITAN TEGANGAN AC

4 TWO EXPRESSION Vm = MAKSIMUM VOLTAGE Vrms= V = Vm/√2 vector representation y(t) is a periodic function of time t, with period T

5 AN IDEAL RESISTOR IN AC CIRCUIT E= Ri i = E/R = (V m /R) sin ωt = I m sin ωtatau I = E/R

6 POWER IN RESISTOR The instantaneous power dissipated

11 11 P is called the average power Q is called the reactive power

12 12 POWER FOR PURELY INDUCTIVE CIRCUITS

13 13 POWER FOR PURELY CAPACITIVE CIRCUITS

14 14 THE POWER FACTOR

15 above 15

16 16 We now calculate P and Q directly

17 17 THE RMS VALUE AND POWER CALCULATIONS
