Can a capacitor hold open an ac relay?

No, because as soon as a load is connected across a capacitor it will discharge. You need a continuous voltage supply across the coil of a relay to keep it energized. Yes. A large capacitor, 10000 mfd, can hold open a small relay for a few seconds, plus or minus, depending on your varibles.

How you using ref relay in transformer?

an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
