Test system and method for induced voltage testing and power loss measurement of high voltage test objects

摘要

Test system for an induced voltage test and power loss measurement of test objects of high voltage engineering, comprising - an energy source (8) for the electrical supply of the test system, - an electrically connected to the energy source (8) motor generator set (10) for adjustment and control of frequency and Voltage within the test system, - a test transformer (11) electrically connected to its primary side (11.1) to the motor-generator set (10), while its secondary side (11.2) is electrically connected to the actual test object (12), the test object (12) is a compensation inductor which forms a constant inductance in the test system, - a continuously adjustable inductance (13) designed as a control inductor on the secondary side (11.2) and a capacitor which can be set in discrete steps and designed as a capacitor bank ( 14) are provided, - the capacitor bank a plurality of individual capacitors (14) which can be connected or disconnected, so that the inductance (13) and the capacitance (14) together with the test object (12) form a series resonant circuit which can be tuned to its resonance point.
