Thiết bị giám sát off line M5400 Doble

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.

Feature:

Instrument sends excitation signals to transformer and measures the returning signals across a broad frequency range
Provides a frequency response measurement from 10 Hz to 25 MHz
Measures frequency response at logarithmically spaced intervals of 1.2%
Auto-scales each frequency measurement for an overall dynamic range of 80 dB with a ±1 dB accuracy
Highest combination of dynamic range and accuracy available
