Software-supported condition diagnosis “Regarding measurements on high- voltage CBs, I really appreciate the fact that after testing, CIBANO 500 and PTM supply me with more infor- mation than I ever had in the past when using other devices for the same measurements,“ Roel van Hees recounts. The PTM software supports the user during diagnostic testing and the condition assessment of var- ious primary assets, including CBs. It provides a well-structured database for managing all asset-related data used for obtaining a comprehensive overview of the asset’s condition. “After a DRM measurement, the graph produced by PTM really gives me a lot of valuable information about a CB’s contacts,” Roel van Hees describes. “The PTM software is also very easy to use and I can adjust all of the parameters for each specific measurement. After the measure- ments, I have an extensive array of options for analyzing the test results,” he explains. “This helps me detect the actual condition of a CB.” Testing HV breakers and GIS with one system “When performing a condition assessment on CBs, the flexibility of CIBANO 500 is very beneficial to me,” Roel van Hees confirms. ”As every measuring parameter is adjustable, I can use the system for measurements on different CB brands and types. This is important when you have a large network with a multitude of different CBs Founded in 1998, TenneT is a leading European electricity transmission system operator (TSO) with its main activities in the Netherlands and Germany. With over 22,000 kilome- tres of high-voltage connections it ensures a secure supply of electricity to 41 million end-users. TenneT discovered CIBANO 500 while looking for new ways to ap- proach proper circuit breaker main- tenance and repair. State-of the-art circuit breaker testing “I am constantly looking for innova- tive approaches to testing that can offer added value,” says Roel van Hees, who works for TenneT as a technical specialist for primary assets in the Southern part of the Neth- erlands. “So, in 2016 after I heard about OMICRON’s circuit breaker test set CIBANO 500, I was given a product presentation. Regarding high-voltage circuit breakers (CBs), we mainly perform timing measure- ments. However, I was amazed to see that this device can also measure the static contact resistance of all the phases of a CB simultaneously,” he continues. “What I liked even more was that without any change in the measuring setup, a dynamic contact resistance measurement (DRM) of all the phases can be per- formed. What finally convinced me to buy a complete CIBANO 500 test set was how easily a measurement can be set up and performed with the Primary Test Manager™ (PTM) software,” he summarizes. 18
