So, the transformer should have a minimum kVA rating of 2 4 4 4 or 402 kVA Refer to the appropriate selection chart A 480 delta primary — 240 delta secondary transformer may be used on a 4 wire, 480Y/277 volt supply The fourth wire (neutral) is not connected to the transformer To not overload the transformer, 480v 3 phase panel, 90 amp 3 pole OCP feeding a 75 KVA 480 delta to 1/8 y transformer, #3 wire size ok to feed ( 75C termination on breaker and lugs ?Transformer taps compensate for high or low line voltages Most standard QL units rated 15kVA through 300kVA and with a primary voltage of 240V or higher have six available voltage taps – four 25% taps below the nominal tap and two 25% taps above the nominal tap This arrangement provides a 15% range of tap voltage adjustment
Capacity of open delta system = √3 x rating of one transformer = √3 x 5 KVA= 866 KVA Capacity of open delta system = 0577 x rating of closed delta system=0577 x 15 KVA= 866 KVA It is the circuit diagram of an open delta system In this diagram three phase unity PF load (resistive load) is supplied by two transformers I have a scenario where there is a existing transformer in the field (no data on the existing transformer) and an adjacent Eaton Panel The nameplate on the panel reads 1/8, 1Ph, 3W Correct me if I'm wrong but the only way to get this voltage is to pull one phase off of a Connect three 1/240v distribution transformers in 1/8 volt configuration The secondary windings of two transformers would be paralleled for 1 volts with one end of each paralleled winding connected to ground and the other ends to phase (A and B) The third transformer would be left in a 1/240v configuration

8 Volts Is A Weird Voltage Where Did It Come From Thermal Corporation
Participants at one of my recent workshops had questions pertaining to reversefed transformers (backfed) The input side was 480 volts (V), threephase, and the output side was 1/8V They wanted to know if the output side of 1/8V transformer could be used as an input side, and if so, how was the electrician to bond and ground the transformer? This means that one of the transformer secondary terminals (usually marked X0) is connected to earth ground and the remaining 3 terminals (usually marked X1, X2, and X3) are each of the three ouput phases On a 1/8 transformer secondary, the voltage measurement from the grounded X0 terminal to any of the other 3 terminals would be 1 VAC Transformer wiring diagrams are printed on the ings are shown connected to form a V delta to /V wye, 3phase, stepdown transformer bank For volt primary to volt secondary, degree temperature rise units the dimensional information, shipping weight, lbs, wiring diagram number A transformer is an electrical apparatus designed to convert
