Product Description

Functional SFRA Analyzer And Transformer Winding Deformation Tester

 

Introduction

• The working principle of GDRZ-902 is to detect whether the transformer is deformed according to the frequency response curve drawn by the test, and provide advice for the maintenance of the test instrument.
• SFRA usually has three measurement methods: time method (comparing the current SFRA result with previous results of the same device), type method (SFRA of a transformer compared with the same type of transformer), and phase-to-phase comparison (one-phase SFRA result) Compare with results from other phases of the same transformer).
• SFRA is mainly used for transformer inspection after short-circuit test, integrity verification of transformer after transportation, condition assessment after high-value transient fault current occurs, routine diagnostic measurement, diagnosis after transformer alarm or protection trip, and monitoring value occurrence Testing after major changes, and further inspection and scientific research after abnormal results of routine tests.
• Our company has designed the winding deformation tester based on the idea and the advanced technique. It could draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer.
