The constants that enter the equations may easily be calculated from transformer data. The equations are valid for transformers with a high-voltage (HV) cylindrical disk winding, and where the turn ratio between the HV winding and the low-voltage (LV) winding is large. Only the natural frequencies in the HV winding are considered. The equations cover windings with the neutral circuit grounded and with the neutral circuit open.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.

For nontransposed lines the induced voltages are a function of all three sequence currents. The positive-and negative-sequence mutual impedance is less than 10% of the self-impedance of the lines while the zero-sequence mutual impedance can be as high as 50 to 70% of the zero-sequence self-impedance of the lines. The conductor configuration should be symmetrical around a vertical axis to avoid differences in the induced voltages in the two circuits.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.

Transducers and instruments available allowed the measurement and recording of many physical variables during these tests. Maximum short-circuit magnitude was 30,000 rms amperes. Short-circuit currents cause dynamic forces to be applied to the bus conductors, hardware, and towers. The major shock force is a result of the twin conductors being pulled together between spreaders by the short-circuit magnetic forces. The number and location of twin conductor spreaders have considerable influence on the peak magnitude of the dynamic forces. Electrical and mechanical damage to conductors as a result of a short circuit was negligible. This suspension bus design proved to be adequate for a shortcircuit duty of 10 million kva (kilovoltamperes) at 220 kv, and with minor modifications it may be adequate for 20 million kva at 220 kv.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.
