FRAX99, Frax101 and Frax150

Sweep Frequency Response Analyzers

  •  Highest dynamic range and accuracy in the industry
  •  Smallest and most rugged FRA instrument in the industry
  •  Fulfills all international standards for SFRA measurements
  •  Advanced analysis and decision support built into the software
  •  Imports data from other FRA test sets

The FRAX series of sweep frequency response analyzers (SFRA) detects potential mechanical and electrical problems that other methods are unable to detect. Major utilities and service companies have used the FRA method for more than a decade. The measurement is easy to perform and will capture a unique fingerprint of the transformer. The measurement is compared to a reference fingerprint and gives a direct answer if the mechanical parts of the transformer are unchanged or not. Deviations indicate geometrical and/or electrical changes within the transformer.

DELTA4000 Series

12 kV Insulation Diagnostic System

  • Power factor test set
  • Automatic and manual operation
  • Accurate and repeatable measurement results with high noise suppression
  • Lightweight, rugged two-piece design
  • New built-in intelligent temperature correction (patent pending)
  • New automatic voltage dependence detection (patent pending)

DELTA4000 series is a fully automatic 12 kV insulation power factor / dissipation factor (tan delta) test set designed for condition assessment of electrical insulation in high voltage apparatus such as transformers, bushings, circuit breakers, cables, lightning arresters, and rotating machinery.
Two configurations make up the Series:

  • DELTA4110 with external computer (not included) consists of the DELTA4100 control unit and DELTA4010 high-voltage unit
  • DELTA4310 comes with onboard computer and consists of DELTA4300 control unit and DELTA4010 high-voltage unit

VAX020

2 kV high voltage amplifier

 

  • Separate high voltage amplifier enables capacitance and dissipation factor measurements at 2 kV test voltage
  • True and proven DFR/FDS technology for highest performance
  • Large frequency range, DC to 1 kHz
  • Compact design, weight < 5 kg

VAX 020 expands the IDAX test voltage range from 200 V to 2 kV. This improves the capability to perform accurate measurements in extreme high interference environments e.g. HVDC substations.

Besides 50/60 Hz capacitance and dissipation factor (power factor) measurements, the application gives valuable information about the general condition of any high voltage insulation by measuring its dielectric response. The technique is also capable of assessing the moisture content in oil/paper insulation systems.
