Product Description

Transformer Sweep Frequency Response Analyzer Winding Deformation Tester

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.

Advantages

1.GDRZ-902 transformer SFRA scanning frequency response analyzer, with a wide frequency scanning range, meets IEC60076-18, and uses ARM processor for processing and output
2.High precision and repeatability, strong anti-interference ability.
3.The equipment is lightweight and compact, making it easy to carry and use on site.
4.Its main function is a color touch screen display, English menu prompts, simple operation, equipped with a high-speed thermal printer, and is designed with a storage function to facilitate data storage and printing.
5.Using data management software, the saved data is transferred to the computer (host computer) via USB for many operations, such as saving, printing, clearing, or operating testing directly through the host computer
6.The built-in non-disposable memory can save 40 groups of winding deformations.

Application

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