IDAS 2823 Capacitance and Dissipation Factor Meter (Tangens Delta)

HAEFELY_2823
Catalog ID: 2823

The High-Precision Dielectric-Loss Analyzing System 2823 is designed for measurement of very low dielectric losses and impedances (Dissipation Factor and Power Factor) of high-voltage apparatus (e.g. extruded insulation on power cables). The instrument works on the principle of a combined bridge-vector-meter and is capable of analyzing capacitive and inductive loads – especially shunt reactors – with outstanding accuracy and stability certified by a leading metrology institute. The use of optically decoupled connection allows complete galvanic isolation between control room and test field, and guarantees the personnel the highest safety level.

FRA 5310

HAEFELY_FRA_5310
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

2903 Oil Test Cell

HAEFELY_2903

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.

SGDA Impulse Generator

HAEFELY_ SGDA

Catalog ID: SGDA

The SGDA impulse generators are the perfect solution for carrying out impulse tests on HV or UHV cables (5 kJ version) as well as on MV and HV power transformers (10 kJ version). Their small footprint and stable design meet the needs of universities and R&D centers. And with its unique Delta-structure, the SGDA impulse generators are easy to transport and erect onsite.The SGDA series are available for 5 or 10 kJ stage energy, with total charging voltages from 400 kV up to 3000 kV. Also, this system features the lowest internal inductance ever achieved and is
