1 3372I 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.

1675Why we use CT on differant phases of 2ph.PT detection for brush-less static excitation of 3ph.,400v Synchronous Generator? What happen if use CT on same one of VT phase?
2 3289hi every body i am master student in control engineering and my project is slip control in trains i assumed a Dc motore as traction motor but i don't have characteristics of this kind of motor that is used in train. i want from every body if he or she has the characteristics or information about Dc motor that is used in train give me those information or technical characteristics .
