SFRA45
Field portable Sweep Frequency Response Analyzer
The SFRA45 is a field portable ‘Sweep Frequency Response Analyzer’ with a bandwidth of 5Hz to 45MHz. Measurement techniques and data formats are fully compliant with IEC60076 Power Transformer testing Part 18 – frequency response requirements. Featuring a high contrast colour LCD screen, DC input power and internal rechargeable battery operation, this tablet style instrument can be used with or without PC Software. Reliable connection to a device under test is assured with a cable reel design unique to N4L and custom connection clamps. Dedicated SFRAComm PC software provides presentation of sweeps recorded live or recalled from the SFRA45 non-volatile memory. The software also includes a database for results storage and fingerprint plot comparison with previous transformer sweeps, plus an automatic health diagnoses test using DLT911 algorithms.Key Features
