Asset managers want to keep medium-voltage cables in service as long as possible without putting security of supply at risk. The BAUR statex® software is designed to support exactly that goal. BAUR describes statex® as software for the statistical estimation of cable life time, using data from dissipation factor measurement (tan delta measurement) together with a patented algorithm to calculate the ageing condition, speed of ageing, and statistical remaining life time of cable routes.
One of the most important points for customers is that statex® is based on IEEE 400.2, but goes much further than the standard evaluation alone. BAUR states that, in addition to the conventional IEEE 400.2 parameters SDTD, MTD, and ΔTD, statex® also introduces the additional parameter TD-Skirt, which reflects the time stability of the dissipation factor. This extra parameter allows the software to calculate the ageing index R and the speed of ageing VR of the cable route, moving beyond a simple category-based interpretation into a more advanced statistical life-assessment model.
That is where statex® becomes especially valuable for utilities and cable network operators. Rather than only indicating whether a cable falls into a broad action category, the software can provide an exact recommendation for when the next measurement should be performed and when work is required on the cable route. BAUR also says the calculation includes the economical operating limit of the cable and a company-specific safety margin, helping users determine the optimal replacement timing based on both technical condition and operational philosophy.
BAUR positions statex® as a key element of condition-based asset management for medium-voltage cable networks. The software gives users an overview of cable condition across the network, supports more targeted measurements, improves investment planning, and contributes to cost reduction and sustainability. The product page emphasizes benefits such as significant potential savings through maximum utilisation of medium-voltage cables, more accurate year-on-year investment planning, and a better overview of the overall cable network condition.
A major strength behind the statex® concept is the statistical foundation of the evaluation model. BAUR says the patented algorithm was developed by KEPCO in collaboration with Mokpo University and validated using 45,000 dissipation factor measurements on 15,000 cable routes, representing about 7,000 km of cable data. This large knowledge base gives the software a far stronger empirical foundation than a simple threshold-only assessment approach.
The software also gives users powerful analysis and visualization tools. BAUR states that statex® provides a 3D illustration of the correlation between normalized dissipation factor parameters such as MTD, ΔTD, and TD-Skirt, helping users understand complex relationships in cable ageing behavior. It can display the historical course of the ageing index and generate results such as the ageing index R, speed of ageing VR, statistical remaining life time, point in time of subsequent measurement, calculated failure date, and 3D status graph.
Another important advantage is flexibility for real utility practice. BAUR says statex® can take into account company-specific guidelines, including limit values for the ageing index R, safety buffers for repair or replacement, and either company-defined evaluation criteria or criteria according to IEEE 400.2. This means the software is not limited to a one-size-fits-all approach. Instead, it can be adapted to the utility’s own reliability strategy, risk tolerance, and maintenance philosophy.
For organizations already using BAUR diagnostics tools, statex® fits naturally into a broader cable diagnostics workflow. BAUR says the software is based on dissipation factor diagnostics with VLF truesinus® voltage and that BAUR diagnostic systems provide the required measurement precision. The software also supports import of BAUR TD measurement data in several file formats and maintains measurement and cable data in a central cable database, making it easier to build long-term condition histories and improve decision-making over time.
The value of this approach becomes clear in BAUR’s comparison between standard IEEE-style evaluation and statex® analysis. According to the data sheet, evaluation of 15,000 cable routes according to IEEE 400.2 classified about 255 km of cable as action required, while the same data evaluated with statex® showed that only about 55 km had a statistical remaining life time of less than 2 years. BAUR says this meant approximately 200 km of cable did not yet need replacement, and KEPCO’s investigations showed an average increase of 11 years in statistical remaining life time compared with evaluation according to IEEE criteria alone. This is a strong example of why statex® can be described as a solution that is based on IEEE 400.2 but goes much further in practical asset management value.
Overall, the BAUR statex® software is a strong solution for utilities and cable asset managers who want more than a standard tan delta interpretation. It starts from the familiar IEEE 400.2 framework, but extends beyond it with TD-Skirt, ageing index R, speed of ageing VR, remaining life estimation, next-measurement recommendations, and company-specific planning logic. For organizations focused on extending cable life safely, reducing unnecessary replacement, and improving medium-voltage asset planning, statex® offers a much more advanced decision-support tool than standard evaluation alone.
