An earthquake activated power interrupting device using a triaxis accelerometer

Philippines is one of the countries situated along the Pacific Ring of Fire that makes it vulnerable to the occurrence of Earthquake and its after effects such as tsunamis. The high probability for an earthquake to hit the country due to its location and due to the unpredictable manifestation of catastrophe motivated the researcher of this study to design an earthquake - activated device that will cut power lines in residential areas especially those which are in nearby bodies of water. The system design of the device was based on the Philippine Earthquake Intensity Scale built in the PHIVOLCS Earthquake simulator including the ranges of ground acceleration and the vibration to the different directions. The proper functionality and reaction of the proposed device was tested and validated in the same simulator.
