Catalog ID: Frequency Response Analyzers FRA 5310
The FRA 5310 is a diagnosis instrument for the detection of mechanical distortions of transformer winding. These distortions can be caused by electro-dynamical forces which appear during short-circuits or by transportation damages during movement.The Sweep Frequency Response Analysis method is based on winding transfer function measured in a wide range of frequency. The system records the transformers _frequency response fingerprint”. Even small winding movements or distortions will cause legible change of transfer curve, which can be detected. Special active measuring probes minimize the influence of test object connecting and earthing which results in |
2914 Solid Test Cell
 |
Catalog ID: 2914 Solid Test Cell The 2914 test cell measures dissipation factor, relative permittivity, and specific resistivity of solid insulating materials such as paper and plastic foils.The test cell is equipped with a shielded measuring electrode which eliminates partial capacitances that influence test results. |
2903 Oil Test Cell
 |
Catalog ID: 2903 Oil Test Cell The precision test cell type 2903 measures the dielectric properties of liquid insulants such as insulating oil, it determines the dissipation factor tan delta and the relative permittivity (dielectric constant) r as well as the specific resistivity.The test cell has been designed as a cylindrical capacitor with a shielded measuring electrode (guard ring capacitor) & thus avoids partial capacitances, which might influence the test results. |
