Description
TDM 45 series which is a revolutionary breakthrough in testing and diagnosis of MV cables. The modular concept allows the engineer to individually set-up the unit based on the type of job that needs to be executed. If e.g. withstand testing on short cable lengths need to be performed then only one module is needed. When part of the task is also to perform a partial discharge diagnosis then an additional module is needed.
Overview of Cable test and diagnosis system-TDM45
- Cable testing, cable diagnosis and sheath testing in one device
- Enables standard compliant high power VLF testing at 0.1 Hz (5 µF @ 40 kVrms)
- Internal tanDelta measurement with automatic result interpretation
- Partial discharge diagnosis using VLF Sine wave, Damped AC or 50/60 Hz Slope technology voltages
- Cable testing, cable diagnosis and sheath testing in one device
- Enables standard compliant high power VLF testing at 0.1 Hz (5 µF @ 40 kVrms)
- Internal tanDelta measurement with automatic result interpretation
- Partial discharge diagnosis using VLF Sine wave, Damped AC or 50/60 Hz Slope technology voltages
TDM45 have three modules depending on user application has to select
- VLF Sinus 45 kV for standard compliant withstand testing of short cables and dielectric loss measurements.
- Boost module:VLF Booster 40 kV for standard compliant withstand testing of long cables up to 20 km length at maximum test voltage and 0.1 Hz test frequency.
- Partial discharge module: PDS 60 for partial discharge (PD) diagnosis, can either be used with the base module only, or also in conjunction with the boost module to perform PD measurements at Damped AC voltages or 50/60 Hz Slope.
TanDelta Diagnostics
- Optional full-fledged, internal tanDelta step test with automatic result interpretation to IEEE 400.2
- Meaningful Voltage Withstand Diagnosis (VLF test and tanDelta diagnosis in one step)
Partial discharge diagnosis
- Powerful database: Simplified searching, browsing and administration of measurement and cable data.
- Fully automatic calibration with the option of calibrating according to cable length or if cable length unknown by propagation velocity.
- Clear display of measurement results and live PD localization. A time-consuming post-processing of the measured data is no longer necessary.
- Phase Resolved Partial Discharge (PRPD) pattern display
- Monitored withstand testing in VLF Sine Wave, VLF CR and DAC mode
- Report generation by mouse click.
