in 2007. The tunnel has three ventilation units of 2 high-performance axial fans each, which are driven by frequency converters. The motors of the fans have nominal operating capacities in the range between 500 and 1,500 kW, which are supplied with electrical energy by their own medium-voltage transformers. These facilities are used for the operation and maintenance of the L\u00f6tschberg Base Tunnel, in normal and incident operation.<\/p>\n\n\n\n<p>EPRO TRAFFIC was commissioned to design and accompany the replacement of the frequency converters that drive the axial fans\u2019 motors. For this purpose, an inventory including on-site inspection was carried out in a first phase, which defined the framework conditions for the preparation of procurement documents. EPRO TRAFFIC supports BLS Netz AG with the preparation and elaboration of technical specifications and the development of the tender\u2019s commercial part. This defines both the criteria for awarding the contract and the technical requirements for the new installations.<\/p>\n\n\n\n<p>After the procurement of the new frequency converters, the implementation planning or the elaboration of the production project is carried out by the manufacturer \/ supplier. In this phase, EPRO TRAFFIC carries out specialist controlling in coordination with the previously created functional specification and the requirements for the new systems contained therein. The development of test criteria for the factory acceptance test is carried out in close coordination with the tunnel\u2019s existing operating criteria.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>After production of the systems, EPRO TRAFFIC will work in close cooperation with all parties involved to develop a script for the installation and commissioning process. This ensures smooth installation during ongoing operation of the tunnel.
