Distribution Automation Handbook - ABB· PDF fileSystem short circuits may produce a relatively intense rate of heating of the feeding transformers. The cop-per losses increase in proportion to the square of the per unit fault current. Table 8.7.1 shows typical dura-tion of external short circuits that a transformer can withstand without damage if the current …[email protected]

BMS Transformers for High-Energy Storage 2: A BMS transformer with a centre tap capacitor and resistor can improve Common Mode Noise Rejection . Although BMS ICs have balanced currents on their I/O pins, most manufacturers recommend a centre-tapped transformer shown in Figure 2. These have been found to improve CMNR if a filter capacitor and termination resistor is used.
