// Given data
// 3-phase distribution system
V = 2300 ; // Line voltage of 3-phase distribution system in volt

V_b = 69000 ; // Common base line voltage in volt
V_pb = 39840 ; // Common base phase voltage in volt

// Calculations
// case a
V_pu_line = V / V_b ; // Distribution system p.u line voltage

// case a
V_pu_phase = V_p / V_pb ; // Distribution system p.u phase voltage
