RSG 482 Recurrent Surge Generator All impulse circuit components may be adjusted in steps. The impulse shape can thus be fine-tuned within a wide range. Additional capacitors and resistors can be connected externally to permit operation with larger impulse capacitances and other resistance values. The peak value of the impulse voltage is stabilised and continuously adjustable. The voltage impulse may be chopped internally within broad limits. The unit also features a continuously adjustable oscilloscope trigger delay which may be set from trigger delay through zero to pre trigger. DESIGN The RSG 482 is a bench-top model which can also be mounted into 19” racks. All input and output jacks are located at the rear panel of the unit. All controls are arranged on the front panel for easy access. BASIC DIAGRAM APPLICATIONS Recurrent Surge Generator 482 is a low voltage equivalent, with one stage only, of a high voltage impulse generator. Its wide range of applications includes the testing of models, the study of voltage distribution in high voltage windings during impulse voltage stresses and the predetermination of the circuit parameters of impulse test plants. Tests can be performed quickly and reliably without endangering personnel. All impulse circuit elements and, therefore, all impulse forms may be varied within broad limits with selector knobs. Due to the repetition frequency of 25 Hz, the voltage impulse may be observed and evaluated on any oscilloscope as a standing image. The unit is especially suitable for: Investigating the impulse voltage distribution in winding models of machines, transformers, reactors and instrument transformers Predetermining impulse circuit data, for instance the value of the front resistance of an impulse generator, which can be performed by connecting the actual test object Non-destructive testing of windings in dry state and under various impulse voltage conditions Insulation fault localisation in windings Investigating transfer characteristics of measuring systems Transient wave measurement in cables and models Training and experimentation in laboratories of technical colleges and electro technical institutes a brand of Haefely is a subsidiary of Hubbell Incorporated. Haefely has a policy of continuous product improvement. Therefore we reserve the right to change design and specification without notice.
