Description
The FRAnalyzer uses the SFRA principle (Sweep Frequency Response Analysis) 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.
Key features
- Reproducible results thanks to innovative connection technology
- Extremely small and compact device (< 1.8 kg / 4 lbs) Wide dynamic measuring range (> 120 dB)
- Fast measurement times (around 30 seconds per measurement)
Applications
The FRAnalyzer is used for transformer testing, after:
- a short circuit event
- transport
- occurrence of high transient fault currents
- a significant change in the monitored values (e.g. combustible gases) or a safety shutdown
The following tests can also be performed:
- Routine transformer condition measurement
- Verification of unusual events determined during conventional testing
