<p>Disclosed is an error detection system for detecting an error in a cooling apparatus (101) mounted in a power converter (4) that drives, for example, a motor (not shown). The error detection system includes a first temperature sensor, a second temperature sensor, and a current sensor. The first temperature sensor measures a representative temperature (Tb) of the cooling apparatus. The second temperature sensor measures an ambient air temperature (Ta). The current sensor measures an input/output current (Im) controlled by the power converter. The error detection system receives measured signals sent from the first temperature sensor, the second temperature sensor, and the current sensor and thereby estimates the performance of the cooling apparatus.</p> |
