UL CERTIFICATION PROJECTS

UL Certification Support of a Medium Voltage, High Current DC Disconnector for the Battery Energy System Storage applications according to standards UL98 and UL98B. This project supported a medium-sized customer in Europe that manufactures disconnectors, switches and cabinets for medium-voltage indoor and outdoor applications. The support covered the UL certification process of a disconnector throughout the preliminary phase, component and construction phases.

This project assessed the feasibility of UL-type certification according to the standard UL347A of the water-cooled medium voltage converter used in chemical, oil, gas and power generation industries that controls high-power applications such as compressors, pumps and fans. This assessment was carried out for a large customer and also contained a separate study for the business case of the UL-type certified medium voltage converter. It assessed the certification of all the components of the medium voltage converter and also the construction of the converter that focused on the clearance and creepage distances in critical areas of the product. 

This project consisted of the update of the existing UL-type certified medium voltage water-cooled converter used in power generation, mining and minerals, marine and oil and gas industry. It was necessary to update the additional cabinets, update of the water-cooling unit and auxiliary transformer. To update the UL file the new components were checked and type tested according to the UL requirements in UL347A agreed by the UL engineer. The update was done within the UL file NJIC.E176716. 

This project was carried out for a large customer with a very challenging timeline. To meet the UL 6141 standard requirements of medium-voltage power converters for wind turbine application some design modifications, component replacements and intensive type test campaigns had to be carried out on the existing PCS product. This project was successfully finished thanks to the professional help and support of our certified project manager, chartered engineer and senior consultant (UL document name ZGFN2.E513716).  

This project was the extension of the previous project of reporting the substance in SCIP (Substances of Concern as such or In complex Products) database and was extended to the whole portfolio of a large customer of medium voltage (MV) converters for mining, marine industry and wind turbine applications. Part of the project was also the maintenance and support of all the activities once the data entered the SCIP database due to upgrades and modernization of the MV converter portfolio.

This project evaluated the products for compliance with EU Regulation REACH (Registration, Evaluation, Authorization and Restriction of Chemicals). It also assessed the compliance to RoHS (Restriction of Hazardous Substances), also known as Directive 2002/95/EC for these two products. Findings were summarized in the report and reported in the SCIP (Substances of Concern as such or In complex Products) database. This project was done for a large customer.

This project was done for a large customer, where project management services were provided to establish a concept for the adaptation of the existing workplace infrastructure in response to the COVID-19 rules and restrictions. It required intensive communication and project management with the different departments, groups, infrastructure services, management and IT department. This project was completed thanks to the vast experience of our senior consultant and project manager.
