GDTL AC Resonant Test System for Generators
● Smaller size,lighter weight compared with same voltage level,same capacity generator AC withstand voltage test equipment.Single equipment is no more than 60kg, easy to move.
● Advanced principle of whole set device and new frequency & inductance modulation technology, strictly ensure generator power frequency withstand voltage test requirements. Wide application scope.
● Equipped with 20Hz-300Hz variable control source. Good protection and output waveform, high stability. With multiple working mode,easy to operate.
● Power supply of 220V or 380V, convenient for on-site power sourcing。
● Max.Q point can be found exactly by the mode of first inductance modulation and later frequency modulation, to avoid resonance deviation because of voltage boosting;
● Flexible configuration and strong extension. Meet all capacitive test object testing requirements in power system.
● Power frequency test mode or Variable frequency test mode.
● Multi-use, cost-effective.
