Ungrounded 480V distribution has been known for serious ground-overvoltage problems for close to 50 years. There is ample discussion at this site. One "reason" for not wanting Y-grounded service is that NEC 230-95 ground-fault protection is required, and that costs a bit more money. This is very poor, short-sighted thinking.High leg delta connection transformer. The voltage between the phases, V AB =V BC = V CA. The phase to neutral voltage can be calculated using the following formula: V AN = V AB / 2. V BN = V AB / 2. V CN = 1.743 * V AN = 1.743 * V BN. If the V AB is 240V, then. V AN = 240/ 2 = 120V.Transformer Size Calculator. When sizing a transformer, you need to know the kilovolt-amps (KVA) that your machine requires. This tool will allow you calculate the KVA that you need. This tool only evaluates common voltages for North America (ie. 24v, 120v, 208v, 240v, 480v, and 600v).
