GR-PD60-2/GR-PDTD60-2
GR-PD60-2 Partial discharge analysis
By a partial discharge analysis with the cable diagnostics systems GR-PD60-2 or GR-PDTD60-2 by GRAMPUS, the dielectric condition of medium voltage cables can be evaluated.
As an expanded device GR-PDTD60-2 comes with an integrated tan delta diagnostics system!
The cable diagnosis system GR-PD60-2 consists of the following units:
- GR-60 AC hipot (optional)
- High voltage filter
- Coupling capacitor
- GR Suite® software for diagnostics and reporting
- Set of cables and corona rings
The total weight for high voltage filter, coupling capacitor and calibrator is 41 kg. Thus the system is perfectly suitable for mobile use.
For partial discharge analysis a sinusoidal 0.1 Hz VLF voltage is employed, adjustable over a range of up to 62 kV peak.
Due to the following features the GR-PD60-2 and GR-PDTD60-2 are the most outstanding systems of their class:
| Compact, lightweight and portable solutions From small, portable units for one-site use (e.g. off-shore) to built-in solutions for “test van” versions. |
| GR Suite® software GR Suite® provides a comprehensive “all-in-one” software solution for testing, diagnosis and management with a comprehensive database. |
| True modularity The GR high voltage generators can be easily up-graded to a diagnostics system, keeping initial investment low. |
| Database Comprehensive GR Suite® database enables easy analysis and evaluation of the PD measurement. |
| Reporting Reporting by a mouse click – simple or comprehensive. |
| Simultaneous measurement
of PD and TD |
- Measurement of the intensity of partial discharges versus time
- Localization of faults by TDR (Time Domain Reflectometry)
- Display of faults in the partial discharges mapping
- Phase related depiction
- Easy to use and language selection
The analysis is documented in the form of a ready-to-use report, containing all relevant results:
- Calibration Pulse (in accordance with IEC 60270) and end detection
- Background noise of the measurement arrangement
- Partial discharges inception voltage (PDIV)
- Partial discharges level at 7 Vo
- Partial discharges extinction voltage (PDEV)
A SINGLE cable diagnostics system for various applications:
- Cables: XLPE, PE, PILC
- Capacitors
- Switchgear
- Transformers
- Rotating machines (IEEE 433)
The GR- PD60-2 or GR-PDTD60-2 enables any test engineer to efficiently perform measurements without extensive training.
