Earthquake Resistance Capability of Voltage Transformer
Publication: Journal of Energy Engineering
Volume 110, Issue 1
Abstract
The damage to power station equipment due to earthquakes has necessitated a study of the dynamic behavior of electrical systems. A 220kv voltage transformer is theoretically analyzed and experimentally tested under steady‐state sinusoidal vibrations. A new test criterion is suggested based on dynamic response of the system during a postulated design earthquake to assess the earthquake withstand capability of the system. Making use of free vibration results of natural frequency and damping of the transformer, the maximum response, which is likely to occur at various locations of the equipment, is evaluated analytically. Shaking table tests are done to achieve the aforementioned design response. A new scheme is suggested to simulate the dynamic loading by equivalent static loading in a rational manner.
