20dB Sweep Frequency Response Analyzer

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
