Use the Doble M5400 Sweep Frequency Response Analysis test set to investigate mechanical integrity of transformers, reactors and other equipment consisting of windings. If you measure the frequency response of a winding then you can identify winding movement.
The M5400 sends an excitation signal into the transformer and measures the returning signals. Comparing this response to baseline readings and results from similar units allows you to identify deviations and confirm internal mechanical problems.
The M5400 reduces the uncertainty about apparatus condition by providing solid evidence of mechanical integrity or winding movement. Use it to help determine how a transformer is deteriorating, if it can go back in service after a fault or if it has been damaged during transit.
Apply the M5400 during factory tests, after transportation, crane delivery, system faults or even routine maintenance in order to get a baseline test result for future evaluations.
Ensure transformer performance, reduce maintenance costs and increase the service life of transformers
Identify problems such as core movement, winding deformation & displacement, faulty core grounds, partial winding collapse, hoop buckling, broken or loose clamping structures, shorted turns and open windings
Use as part of your regular maintenance program or any time you suspect a problem
Measurements are highly repeatable so even subtle changes can be used for diagnostic purposes
SFRA Measurement Cables
The SFRA measurement cables comply with FRA measurement requirements according to IEC 60076-18. Two cable kits are available.
SFRA Classic Plus
This is the default cable shipped with the M5400 in the 18 m (60 ft) length, with classic 3.6 m (12 ft) fixed-length ground connection. It provides ring-style reference ground connection for shorted lead testing and IEC 60076-18 FRA Method 1 (shortest braid) grounding technique with optional braid kit.
IEC 1 with Braid Kit
Use the IEC 1 kit if you test only by the IEC 60076-18 Method 1 technique (shortest braid). The braid kit allows you to test on bushings up to 800 kV level.
