Product Description Product DescriptionSweep Frequency Response Analyzer Model: FRA100DescriptionPower transformers are some of the most vital components in modern transmission and distribution infrastructure. Transformer failures cost enormous amounts of money in unexpected outages and unscheduled maintenance. It is important to avoid these failures and make testing and diagnostics reliable and efficient.Sweep Frequency Response Analyzer was developed for testing the integrity of power transformers after transportation or occurrence of high currents. 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 Features1)Use SFRA(Sweep Frequency Response Analysis) to test winding deformation by measuring each winding's amplitude-frequency response characteristics of power transformers(6kV and above voltage grade) without hang cover or disassembly.2)Quick measuring: the measurement time of single winding is less than 2 minutes.3)High frequency accuracy: ≤0.001%4)Maximum sweep points up to 50,0005)Digital frequency synthesis to ensure higher frequency stability6)5000V voltage isolation to protect laptop fully 7)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.8)Analysis software has powerful function which can fulfills requirements of Chinese standard DL/T 911-2016 and international standard IEC60076-18:2012.9)Software management possess high humanization and intellectualization. Users only need to click one button to complete all measurements after parameters setting.10)Small size and light weight(2.3 kg / 5.07 lb) for easy carryTechnical Data Measurement SectionParameterSpecificationTest MethodSFRA (Sweep Frequency Response Analysis)Frequency Range10Hz - 10 MHzFrequency Resolution< 0.01%Frequency Inaccuracy≤ 0.001%Number of PointsDefault 600, user selectable up to 50,000 pointsMeasurement Time1-2 minutes per single windingPoints SpacingLogarithmic or linearSweep SettingsCustom frequency bands (linear/logarithmic scale)Dynamic Range-120dB ~ +20dBInaccuracy±0.1 dB (+10dB to -50dB)±0.5 dB (-50dB to -80dB)±1 dB (-80dB to -100dB)PC CommunicationUSBSoftware CompatibilityWindows XP/7/8/10Standards ComplianceCigre Brochure 342 (2008)DL/T 911-2016IEC60076-18:2012Weight2.3 kg / 5.07 lbAnalog OutputChannel: 1Compliance voltage: 0.50-25 Vp-p, adjust automatically in testMeasurement voltage at 50 Ω: 0.25-12.5 Vp-pOutput impedance: 50 ΩFrequency range: 10Hz-10MHzSweep direction: low to highAnalog InputChannels: 2Sampling: SimultaneouslyFrequency range: 10Hz-10MHzInput impedance: 1 MΩSampling rate: 100 MS/sPC Requirements(PC not included)Operating system: Windows XP/7/8/10 Processor: Pentium 500 MHz or higherMemory: 256 Mb RAM or moreHard drive: Minimum 30 Mb freeInterface: USBGeneral AC power supply for adapter: 100-240V AC, 50/60Hz DC power supply for instrument: 12V DCDimensions: 238 x 184 x 40 mm (9.37" x 7.24" x 1.57")Weight: 2.3 kg (5.07 lbs)Environmental ConditionsApplication field: The instrument is intended for use in medium and high-voltage substations and industrial environments.Storage temperature: -20°C to 70°C (-4°F to +158°F)Operating temperature: -20°C to +50°C (-4°F to +122°F)Humidity: < 95% RH, non-condensingSafety Qualifications and EMCSafety: designed in accordance with IEC61010-1, 2006/95/ECEMC: 2004/108/ECSweep Frequency Response Analyzer FRA100 is ideal instrument for detecting mechanical and electrical changes of the core and winding assembly of power transformers.
