Diagnose of Electric Power Transformer's Dynamic Stability State with Low-voltage Reactance |
| |
| Abstract: | Based on an example, before transformer leaves the factory, after transportation and short-circuit current, using low voltage reactance law to check the electric power transformer winding and the iron core's dynamic stability state parameter method is suggested. Comparison on several kinds method has given, and has pointed out whose effect and significance respectively. |
