Concept:
For a transformer, the input impedance (Zin) for a given load impedance (ZL) is given by:

Where Zin is also called the Reflected impedance since it appears as if the load impedance is reflected in the primary side.
Calculation:

Therefore the value of capacitance seen across the primary is:
