The acoustic waves induced by PD could be measured and used for monitoring
diagnosis and locating of the potential failures in power transformers. In this paper
Finite element analysis(FEA) simulation models for partial discharge acoustic wave propagation are built. The behavior of the acoustic wave propagation using the simplified models is analyzed. The PD acoustic wave propagation simulation results are compared with experiment using PZT sensors. The theoretical derivations and computer simulations show consistency with experiment results in 1-D case.
