Abstract: High-voltage switchgear status assessment technology is one of the key technologies to realize the true intelligent highvoltage switchgear. Introduction was made to acoustic fingerprinting technology and its importance in machinery status assessment of high-voltage switchgear. This paper analyzed the device status information hidden in acoustic fingerprint signal and extracted the characteristic parameters by modern information processing technology. The machinery condition assessment system of high-voltage switchgear initially achieved based on multiple parameters in laboratory environment.
         Key words: smart high-voltage switchgear; acoustic fingerprinting; status assessment; smart substation
