NEDO project have developed a monitoring system for early fault detection and ensuring soundness of the pumps used in heat supply facilities. The feasibility study is obtaining the cause and effect relationship of faults. This paper presents the result of test conducted in which imitational fault was introduced to understand actual operating conditions and measuring vibration acceleration, etc. The failure of bearing increased current value, surface temperature, vibration acceleration and power spectrum of vibration acceleration. In addition, we verified that it can detect the failure using the piezoelectric MEMS energy harvester.
