Question 5. The approximate equivalent circuit of a three-phase ∆ /∆ connected 60 Hz, 4000/1000 V transformer reduced to the primary and its parameters are as follows. It is given as Z'y=7.75+j5.85 Ω. A voltage of 4000 Volt is applied to the primary winding of this transformer. Accordingly, calculate the values of primary line current, secondary line current, secondary line voltage and total input and output power for the three phases. 1-) If 4000 Volt voltage is applied to the primary of the transformer above, enter the amplitude value of the primary line current in the box below. ( Phase value will not be entered, for example, if the amplitude is 150 Volts phase is 36.86 degrees, only 150 will be entered!!! 2 digits after the comma will be enough. ) 2-) If 4000 Volt is applied to the primary of the transformer above, enter the amplitude value of the secondary line current in the box below. ( Phase value will not be entered, for example, if the amplitude is 150 Volts phase is 36.86 degrees, only 150 will be entered!!! 2 digits after the comma will be enough. ) 3-) If 4000 Volt is applied to the primary of the transformer above, enter the amplitude value of the secondary line voltage in the box below. ( Phase value will not be entered, for example, if the amplitude is 150 Volts phase is 36.86 degrees, only 150 will be entered!!! 2 digits after the comma will be enough. ) 4-) If 4000 Volt voltage is applied to the primary of the transformer above, enter the three-phase total input power value in kW into the box below. ( 2 digits after the comma will be enough. ) 5-) If 4000 Volt voltage is applied to the primary of the transformer above, enter the three-phase total output power value in kW in the box below.
