Product Description

Low Price Power Transformer Sweep Frequency Response Analyzer SFRA Tester
 

Product Description

 

Introduction

GDRZ-902 Sweep Frequency Response Analyzer (SFRA) is a technology used to evaluate the mechanical and electrical performance of power transformers and generators. It detects mechanical and electrical faults in the equipment, such as coil misalignment, broken strands, loose joints, insulation damage, etc., by measuring the response of the equipment over a range of frequencies.

Application

For testing the mechanical integrity of transformers, such as cores, windings and compression structures.
For testing transformer windings for damage or deterioration.
For detecting any mechanical or electrical changes in the transformer
For testing the mechanical and electrical integrity of transformers after transport or after exposure to high fault currents.
