Claim 0:
1. A condition monitoring system for monitoring at least one electrical power component, comprising:
a partial discharge detector configured to detect partial discharges from the at least one electrical power component and comprising at least one acoustic sensor for detecting acoustic signals of the partial discharges;
a processing unit configured to process the acoustic signals detected by the acoustic sensor, detecting an incidence rate of the partial discharges detected by the acoustic sensor, outputting an incidence rate signal, and determining a time characteristic of the incidence rate from the incidence rate signal and a time signal; and
an analysis unit configured to monitor the time characteristic for at least one of fall and rise, and to trigger a warning signal when a settable threshold is exceeded.
