Keeping in tune with genset harmonics: Generator sets come in various forms, so it is essential the end user chooses a set with the correct power rating, writes Anna Currie, technical and operations manager at LCH Generators

摘要

Transportable diesel generator-sets have become an indispensable item of plant for almost every kind of civil engineering project, providing temporary mains-independent power to operate all types of electrical equipment. This can range from fluorescent lighting, computers and commercial equipment in the site offices to security systems, electrically powered tower cranes, mixers and a wide variety of heavy-duty industrial power tools and on-site equipment. Regarded almost as a 'fit and forget' item, which merely needs periodic re-fuelling and minimal maintenance, the diesel genset is expected to operate continuously, quietly, efficiently and with total reliability for extended periods, often under arduous conditions. While leading specialist generator hire companies can meet these expectations for almost any on-site power requirement, it is vital the client provides the relevant information to enable the correct size of generating-set to be selected to avoid commercially painful pitfalls.
