Sweep Frequency Response Analyzer
Model: FRA100
Sweep Frequency Response Analyzer FRA100 uses the SFRA(Sweep
Frequency Response Analysis) method and measures the electrical
transfer function in a wide frequency range. It detects winding
defects and faults in the magnetic core-thereby helping to improve
transformer reliability, reduce maintenance costs and prevent
costly failures.
Sweep Frequency Response Analyzer FRA100 fulfills requirements in
Cigre Brochure 342,2008 mechanical condition assessment of
transformer windings using FRA and Chinese standard DL/T 911-2016,
FRA on winding deformation of power transformers, as well as
international standard IEC60076-18:2012.
Main Features
●Use SFRA(Sweep Frequency Response Analysis) to test winding
deformation by measuring each winding’s amplitude-frequency
response characteristics of power transformers
●Quick measuring: the measurement time of single winding is less
than 2 minutes
●High frequency accuracy: ≤0.001%
●Maximum sweep points up to 50,000
●Digital frequency synthesis to ensure higher frequency stability
●5000V voltage isolation to protect laptop fully
●Able to load 9 curves at the same time and automatically calculate
parameters of each curve to diagnose winding deformations and
provide the reference conclusion.
●Analysis software has powerful function which can fulfills
requirements of Chinese standard DL/T 911-2016 and international
standard IEC60076-18:2012.
●Software management possess high humanization and
intellectualization. Users only need to click one button to
complete all measurements after parameters setting.
●Small size and light weight(2.3 kg / 5.07 lb) for easy carry
