parallel wiring

I am an American living in Vietnam and I have recently gotten a refrigerator from Japan and it is rated for 100 vac, but the power here is 220 so I bought a voltage stabilizer it has a 1 kva output rating. Can you please tell me what the amperage is? I'm confused and without a working fridge.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
