Piping vibration or damage caused due to dynamic loads, such as mechanical vibration, acoustic vibration, fluid hammer, pulsation and relief valve discharge. 由于动荷载引起的管道震动和损坏，例如机械震动，声波震动，液击，压力脉动和泄放阀门泄放时引起的震动。
In fact, the loading on a typical installation can be many times higher than the discharge capacity of a typical varistor type arrester. 事实上，在一个典型防雷装置上的负荷，比一个典型的压敏电阻型保护器的泄放能力，有可能高出许多倍。
