Using Voltage Regulation to find load capacitance (Transformer)

[Maccca]

Hi,
I did an experiment, involving transformers. Where we did open circuit and short circuit tests then test with a resistor, capacitor and inductor.

For the last question it asks Calculate the load capacitance and inductance from the voltage regulation readings.

Voltage regulation readings were: Capacitors -

Initial Voltage (Switch off) Final Voltage (Switch on) Voltage Regulation
110.2 V 110.5 V -0.271%

Inductors -

Initial Voltage (Switch off) Final Voltage (Switch on) Voltage Regulation
110.4 V 110.1 V 0.272 %


THREE LOADS
Capacitors -

Initial Voltage (Switch off) Final Voltage (Switch on) Voltage Regulation
110 V 110.9 -0.812 %

Inductors -

Initial Voltage (Switch off) Final Voltage (Switch on) Voltage Regulation
110 V 107.9 V 1.95 %

Help please I think i am missing something because I am not sure of the linking formulea.

From the open circuit and short circuit tests, you should have derived a Thevanin's Equivalent, then use the equivalent with the loads. I think that's what you are missing.
