The BAUR Frida TD is a portable high-voltage device for testing and diagnosing medium-voltage cables that combines advanced VLF (Very Low Frequency) testing functions with integrated measurement of the dissipation factor (tan δ) and the Monitored Withstand Test (MWT) in a single automated sequence. This allows both dielectric strength tests and detailed insulation diagnostics on cables with plastic insulation (PE/XLPE) or paper-insulated cables, enabling an accurate assessment of cable condition and its dielectric aging in a single measurement process. The Frida TD is optimized for out-of-service testing on medium-voltage networks up to 20 kV, simplifying test setups and reducing operational times without compromising result quality.
Frequently Asked Questions
What capabilities does the BAUR Frida TD integrate?
The Frida TD integrates:
VLF test with truesinus® technology to apply low-frequency test voltage with minimal distortion.
Dissipation factor (tan δ) testing to assess insulation aging.
Monitored Withstand Test (MWT) que combina ensayo de resistencia dieléctrica y medición de tan δ en un solo proceso automatizado.
This allows obtaining complete results of the cable condition with a single test sequence.
What advantages does VLF truesinus® technology offer in testing?
The VLF truesinus® technology generates a low-frequency sinusoidal voltage with low distortion and reproducibility independent of the load, which allows detecting insulation faults without subjecting the cable to extreme voltages that could deteriorate the dielectric material during the test.
What types of cables can be evaluated with the Frida TD?
This equipment is suitable for diagnostic testing of medium voltage cables with plastic insulation (PE/XLPE) and impregnated paper, allowing differentiation between new cables, cables with minor damage, or with advanced damage such as that caused by 'water trees'.
How does the dissipation factor (tan δ) improve the diagnosis of insulation?
The measurement of the dissipation factor (tan δ) provides detailed information about the deterioration of dielectric insulation that is not always evident with a simple voltage test. Higher tan δ values may indicate aging, moisture, or internal degradation, allowing maintenance actions to be prioritized before catastrophic failures.
What benefits does the automation of testing and diagnostics offer?
The automatic test and diagnostic sequences of the Frida TD reduce human error and operation time by performing repeatable and consistent tests without the need for manual intervention between measurements. This optimizes the efficiency of the cable condition measurement and analysis process in the field.
