Analyzing Critical Bolting Factors to Inverter Failures
A common response to Inverter failure due to loosened bolted connections: the installer simply didn’t torque it properly. While this is certainly a possibility it is difficult to truly know the real root cause after the event has already happened without some intelligent monitoring system in place each bolted joint (which in reality today there is no cost-effective way to accomplish this). We will be discussing several critical factors that influence bolted joint integrity in this application including joint settlement, relaxation, and vibrations.
