M5300

Product catalog summary

Overview: The M5300 is a Sweep Frequency Response Analyzer (SFRA) designed for diagnosing transformer core and winding movement. It detects mechanical failures or movements due to short circuits, mechanical stresses, or transportation, ensuring transformer performance, reducing maintenance costs, and increasing service life.

Key Features:

Technique: Utilizes Sweep Frequency Response Analysis, a proven method for accurate and repeatable measurements, becoming the industry standard for frequency domain measurements.
Functionality: Sends an excitation signal into the transformer and measures returning signals across a broad frequency range to identify deviations and confirm internal mechanical problems.
Applications: Diagnoses issues such as core movement, winding deformation, faulty core grounds, partial winding collapse, hoop buckling, broken or loosened clamping structures, and shorted turns and open windings.

Technical Merits:

Frequency Range: 10 Hz to 25 MHz, with a recommended diagnostic range of 20 Hz to 2 MHz for transformers.
Resolution: Measures frequency response at logarithmically spaced intervals of 1.2%, maintaining a constant excitation level for each frequency measurement.
Repeatability: High-quality, repeatable measurements with a dynamic range of 80 dB and ±1 dB accuracy.
Test Leads: Robust and reliable test leads for site testing.

Technical Specifications:

Excitation Source: 1 channel, 20 V peak-to-peak output voltage, short circuit protected, 50 Ohms source impedance.
Measurement Channels: 2 channels, simultaneous sampling, 10 Hz to 25 MHz frequency range, 100 MS/s max sampling rate.
Data Collection: Sweep Frequency method, USB/Ethernet communication, 1000 to 1800 points, 1.2% logarithmic point spacing.
Physical Specifications: Dimensions: 10.0 H x 16.0 W x 15.5 D in, Weight: 22.5 lbs, Operating Temperature: 0° to 50° C.

Practicality: Supported by Doble’s Client Service Engineers, leveraging decades of field experience to ensure effective use of SFRA measurements.

Additional Information: The M5300 includes a built-in PC with Windows XP, Intel Celeron 1.3 GHz, and minimum 512 MB RAM. It is portable with a carrying strap for easy transportation.
