  Live Tank Circuit BreakersRoutine testing  2 | ABB Live tank circuit breaker routine testing Routine tests Live tank circuit breakers   ABB Live tank circuit breaker routine testing | 3  All circuit breakers are tested  ABB has a well established process to ensure on-time delivery of circuit breakers to its customers with the highest level of quality and reliability. At the live tank circuit breaker produc-tion facility in Ludvika, over 3000 circuit breakers are manu-factured and routine tested annually. The routine tests are performed for the purpose of ensur-ing the quality and guaranteed performance of the material, design and assembly of the circuit breaker and are made on each apparatus manufactured. We welcome customer witnessing of these tests. The routine tests are part of the process of producing the circuit breakers and are always per-formed with the same test procedures, irrespective whether or not the tests are witnessed by the client’s representative. Performance of routine tests  The main steps of the order process related to routine testing are described in the example timeline shown below. The exact timing of these steps may vary depending on the size and complexity of the order.  An invitation to witness routine testing is part of the order acknowledgement, when planned dates for routine testing and shipping are given. Confirmation is sent to the customer normally six weeks before the planned routine test dates.When the final dates have been advised, participation of any inspector(s) shall be confirmed by the customer at least three weeks before the planned dates for routine tests. Any requests for special or additional test procedures shall always be advised well in advance, preferably with order placement, but at the latest with the confirmation of witness-ing participation.It must be noted that any requested changes to the test process or the planned date for routine testing will affect the deli very time. After each routine test, a test review meeting is held together with the client's witness in order to summarize the tests, documentations and for resolving any questions which may have arisen during tests.For each circuit breaker a complete routine test report, approved and certified by an ABB test supervisor, is issued and distributed to the customer as part of the order documentation.

Many items are also routine tested in advance by the suppliers in accordance with ABB instructions, the documentation for which can be shown on request. Breaker pole, Mechanical and Electrical assembling  Tests are also conducted on major modules of the circuit breaker during the factory assembly process, prior to the final routine testing of the complete circuit breaker poles and operating mechanism(s). Any non-compliant components are clearly marked and isolated from production for further analysis. Routine test  The final routine test process is described further on pages 6 and 7. Packing  After completion of routine testing the circuit breaker is disas-sembled into its shipping modules for packing. Delivery to customer   After packing the circuit breaker is shipped to the customer according to agreed order requirements.
