BAUR frida TD VLF Testing and Diagnostics for Medium Voltage Cable Assessment
Medium voltage cable networks require reliable testing and diagnostics to maintain service continuity and reduce the risk of unexpected failures. The BAUR frida TD is designed as a portable VLF testing and diagnostics unit for offline testing and diagnostics in medium-voltage networks. BAUR positions it as a solution that combines cable testing and dissipation factor measurement in one device for more accurate and comprehensive cable condition assessment.
The frida product family is available in two configurations, frida and frida TD. The standard frida is used for cable and cable sheath testing of medium-voltage cables and electrical equipment up to 20 kV, while the frida TD expands the functional scope with integrated tan delta diagnostics and Monitored Withstand Test (MWT). This added functionality makes frida TD the stronger choice for users who need both testing and deeper cable condition evaluation in one platform.
A major advantage of the BAUR frida TD is its ability to combine VLF cable testing with truesinus 0.1 Hz up to 26 kVrms / 36 kVpeak, integrated dissipation factor diagnostics tan delta, and MWT with tan delta. BAUR also notes that the unit can be used for partial discharge measurement when combined with the PD-TaD 62 and BAUR Software 4, allowing users to build a more complete picture of cable condition.
For cable asset managers, one of the most valuable functions is the dissipation factor measurement. BAUR states that tan delta measurement with 0.1 Hz VLF truesinus provides differentiated information on the ageing condition of paper-insulated mass-impregnated and PE/XLPE cables. For PE/XLPE cables, it can help distinguish between new cables and those that are slightly or severely affected by water tree damage, making it easier to prioritize cable replacement and maintenance decisions.
The Monitored Withstand Test is another important benefit of the frida TD. BAUR explains that MWT combines cable testing and dissipation factor measurement in a single sequence, providing a more accurate and comprehensive assessment of cable condition while keeping stress on the cable low through an optimized test duration. For utilities and service providers, this means a more efficient workflow and better information from a single test process.
The BAUR frida TD is also built for practical field use. BAUR highlights easy and quick test assembly, automatic testing and diagnostic sequences, and compact dimensions with lightweight construction. The datasheet lists the unit at approximately 22 kg, with dimensions of 438 x 456 x 220 mm, making it portable enough for field testing while still delivering a maximum output voltage of 26 kVrms.
From a technical standpoint, the frida TD supports VLF truesinus, VLF square wave voltage, and DC voltage. It offers a frequency range of 0.01 to 0.1 Hz, load range for VLF testing from 1 nF to 8 µF, and dissipation factor measurement on medium-voltage cables up to 20 kV. BAUR specifies tan delta resolution of 1 x 10-6 and measurement precision of 1 x 10-4, supporting highly precise diagnostics for cable evaluation.
The system is designed to support recognized testing practices as well. BAUR lists cable testing according to IEC 60060-3, IEC 60502.2, CENELEC HD 620/621, IEEE 400-2012, and IEEE 400.2-2013, while cable sheath testing is specified according to IEC 60502 / IEC 60229. For organizations that need standardized procedures and repeatable results, this standards support is an important advantage.
Another strength of the BAUR frida TD is its software integration. BAUR Software 4 can be used for remote control of the frida TD and for office-based evaluation of measurement results. BAUR says the software helps users carry out efficient measurement processes and consistent cable condition evaluation, supporting condition-based maintenance strategies for medium-voltage cable networks.
Overall, the BAUR frida TD is a strong solution for utilities, cable service providers, and testing specialists who need more than a standalone VLF tester. By combining cable testing, tan delta diagnostics, MWT, and optional partial discharge measurement, it supports a more complete and efficient approach to medium-voltage cable assessment. For teams focused on cable reliability, smarter maintenance planning, and better asset condition insight, the frida TD is a powerful diagnostic platform.
