Sweep Frequency Response Analyzer for Power Transformer Winding Diagnosis
The FRAnalyzer detects defects in power transformer windings and faults in the magnetic core. After the transport of transformers to site and following through faults with high currents the frequency response test should be made to ensure that the windings were not damaged.
Unique features of FRAnalyzer
• High reliability of results due to the applied measurement method and innovative connection technique
• Extremely small size through the use of leading edge technology
• Ease of use because of creative software
• Portability resulting from battery operation
Measuring Modes
The basic functionality of FRAnalyzer supports the following measuring mode (amplitude and phase):
• Voltage transfer function Uo/Ui (f)
With the integral vector network analyzer toolkit the following additional functions can also be measured:
• Impedance Function Ui/Ii (f)
• Admittance Function Ii/Ui (f)
