Beskrivelse

The cable diagnosis system PD90-2 consists of the following units:

HVA90 insulation tester (optional)
High voltage filter
Coupling capacitor
b2 Suite® software for diagnostics and reporting
Set of cables and corona rings

The total weight for high voltage filter, coupling capacitor and calibrator is 47 kg. Thus the system is perfectly suitable for mobile use.

For the partial discharge test a sinusoidal 0.1 Hz VLF voltage is employed, adjustable over a range of up to 90 kV peak.

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.

b2 Suite® software
b2 Suite® provides a comprehensive “all-in-one” software solution for testing, diagnosis and management with a comprehensive database.

True modularity
The b2 high voltage generators can be easily up-graded to a diagnostics system, keeping initial investment low.

Database
Comprehensive b2 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
The parallel testing and measurement of PD and TD saves a significant amount of time, and prevents preconditioning of the cable.

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 partial discharge test 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 1.7 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 PD90-2 enables any test engineer to efficiently perform meausrements without long training periods.
