Why Choose the Megger FRAX200?
The Megger FRAX200 measures the frequency response of transformer windings and cores by injecting a swept sine wave and analysing the resulting signal. The measurement creates a reference ‘fingerprint‘ that can be compared with previous results to identify internal mechanical changes over time.
Designed for field and workshop use, the Megger FRAX 200 combines high measurement accuracy with simple operation. Features such as built-in demagnetisation, automatic ground loop checking and Bluetooth connectivity help improve testing efficiency while reducing the risk of inaccurate results.
Megger FRAX200 Key Features:
The Megger FRAX offers a range of features designed to simplify transformer diagnostics, including:
- Sweep Frequency Response Analysis from 0.1 Hz to 30 MHz
- Built-in adaptive demagnetisation for improved low-frequency measurements
- Automatic ground loop verification before every test
- USB-C and Bluetooth Low Energy (BLE) communication
- Battery-powered operation for convenient field testing
- Optional FSX200 switchbox for one-time connection to all transformer phases
- Intuitive Windows software with automated curve comparison and reporting
These features help deliver consistent, repeatable results while reducing overall testing time.
Detect Hidden Transformer Faults
The Sweep Frequency Response Analyser is capable of identifying a wide range of transformer defects that may not be visible using conventional electrical testing.
Common applications include detecting:
- Winding displacement
- Winding deformation
- Shorted or open windings
- Core movement
- Faulty core grounds
- Broken clamping structures
- Partial winding collapse
By comparing current measurements with previous baseline tests, the Megger FRAX200 helps engineers identify developing faults before they affect transformer reliability.
