HVAC serial resonant test systems with oil insulated modular reactor in variable inductance, operating in power frequency 50/60Hz, for testing of gas-insulated switchgears up to 1600 kV in accordance with IEC 62271-203.
Oil-insulated Modular Reactor AC Resonance are designed to compensate capacitance in testing circuit precisely by adjusting inductance of HV reactors, and output continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.
They use resonance between capacitive test object and inductive HV reactor of test system, adjust inductance of HV reactor to form a series resonant circuit with test load, resulting in an ideal sinusoidal resonance voltage. The natural resonance frequency of test circuit is matched to feed-in mains frequency 50/60 Hz by tuning inductance of HV reactor.
The oil-cooled HV reactor is installed in a closed container made of steel and insulating cylinders.
The module setup enables you to connect the reactors in series or in parallel for extending the range of voltage and/or current. The individual modules can be installed above or next to one another.
As part of a series resonant circuit, these systems provide undistorted high voltage. And because the systems are designed to have high quality factor (Q), low input power is required (1/Q) which results in lower installation and operating costs.
