| Years: 2004 to 2007 | Employer: Siemens LDA | Title: (Undisclosed) | Department: (Undisclosed) |
Responsibilities:• Specified LV and MV power components (e.g. 3 Phase Motors, Power Transformers, Inverters) that were used in VSD based projects. Components would need to meet customer, and relevant engineering standard(s), requirements. This would often involve frequency and/or time domain modelling the system.• Provided engineering services as required e.g. Fault Studies, Harmonic studies and/or site surveys, support of other departments in meetings. • Provided technical support to other departments (Sales, Customer Service, Project Management and Applications Engineering) on a wide variety of topics including component sizing, field data analysis, solution definition and project calculations. • Worked on design and coding of engineering software tools/windows applications, using VB.NET 2005. Used and extended a variety of .net controls and classes (including GDI+, Reflection, XML and .net language features) for the interface, file management, printing and simulation engine. Worked with users to define and refine requirements, and agree their timescales. |
