Power Systems Get Transient-load Analysis

摘要

The Sentinel RingDown EPU (electronic-prognostic unit) from the Ridgetop Group predicts power-supply-system failures by externally monitoring transient response to source or load changes. Transients on a power supply's voltage rails produce "ringing" waveforms that are characteristic of the power system's health. This approach enables pre-emptive condition-based-maintenance strategies for critical systems and devices. RingDown requires no modification to the power-supply circuit: It uses a power supply's externally available power- and output-load lines. It also works with dc brushless motors and electromechanical actuators.
