Abstract :
NTT´s telecom buildings are equipped with emergency engine generators for use in the event an outage occurs in the commercial power supply. To ensure they are in proper operating condition, these engine generators must be tested to inspect their starting capability at regular intervals of one to three months. This paper discusses the results of verification tests conducted on pseudo-malfunctions using a method that quantitatively detects abnormal engine conditions through frequency analysis of engine sound
