FROM NEWCOMER TO TECHNOLOGY LEADER 10 Years of CIBANO 500 Was the CIBANO 500 designed specifically for testing high-voltage circuit breakers? Stefan Achberger: The focus on high-voltage equipment resulted from stringent demands placed on testing these circuit breakers. Connecting large breakers is very time-consuming. The terminals are several meters above ground, so we have to use ladders or risers. It quickly became apparent that the tests had to be feasible without any rewiring, with as few cables and components as possible. To ensure the safety of our customers at all times, we also must be able to test the circuit breakers with both sides grounded. The result was a modular concept using the CB MC2s. These modules only weigh 1.2 kg (2.64 lb) with a single connection to the main device and short connecting cables to the breaking elements. Compared with other systems, this concept was simpler and needed less than half the testing time required by typical circuit breakers in a high-voltage application. Nowadays, we can also test more sophisticated breakers with four or more breaking chambers per phase without any rewiring. We produced a video that shows how a breaker like this is connected and tested: In the previous edition, we asked a Dutch testing provider why they chose our circuit breaker test system several years ago and whether they were satisfied with it. Today, we’re going to look at CIBANO 500’s history over the last ten years. OMICRON Application Engineer Stefan Achberger is someone who knows all the ins and outs of the system for years. In our interview, he explained the development of the device from its launch to the present day. 18
