As to transient overvoltages it is safe, and in the larger sizes has the advantage of lower cost and smaller space as compared with a resistor. ... 24 (b) three potential transformers are connected in star, and function in a similar manner. ... ( 6) Zero-sequence diagram showing how zero-sequence voltages may be transferred from the high-voltage to the low-voltage side of a transformer where the low-voltageanbsp;...
