A number of tests are carried out during manufacture and after assembly of large turbo-compressor strings. This paper focuses on full load, full speed, and full pressure tests of large electrical driven compressor strings with power consumptions up to 100 MW. Testing of these systems, including not only the motor but the complete VSD system requires careful planning, scheduling and arrangement of the equipment to be tested. Based on the customer's specific requirements, test procedures need to be prepared and discussed in advance, including the definition of the tests to be performed, the sequence of testing as well as details of the test instrumentation and data acquisition. The tests will be carried out in accordance with the applicable standards, e.g. ASME, DIN, and API to ensure a maximum of quality assurance for the equipment delivered to site. Therefore, such a testing is one of the most important milestones in order to minimize the risk on site.
