Converter valves play a pivotal role in high-voltage direct current (HVDC) transmission systems as they convert power between alternating current (AC) and direct current (DC) forms to meet the demands of modern power systems. The vibration exhibited by the converter valve serves as a vital parameter for assessing the condition of the HVDC system while also presenting an ambient resource that can power Industrial Internet of Things (IIoT) sensors, enabling them to perform diverse tasks. In this work, we compare and characterise for the first time the vibrations of two types of HVDC converters under the same operating conditions. Furthermore, by reproducing the vibrations in the field, we evaluate the behaviour of the vibrational energy harvester in different axial directions under these two kinds of converters. Our study showcases its promising potential as a standalone energy source for IIoT devices.
