Phase Phase constant value of 480 volts, 50 Hz balanced, 3 phase source through fixed 50 ohms a load will be fed by a 3-phase AA voltage controller. Thyristor in positive alternans in phase , It is known to be triggered at,160o ,220o and 240 o. 

Calculate the active phase-neutral voltage and the power transmitted to the load on these 3 trigger states given
