Product Description

General introduction
GDTF series Substation Electrical Apparatus AC Resonance Test System, is mainly composed of frequency conversion control power, incentives transformers, reactors, capacitor divider, designed for substation electric
Equipment AC withstand voltage test of the voltage with 220KV or below. It satisfy capacitive equipment AC withstand voltage test of transformer, GIS systems, SF6 switches, cables, casing.
This Series can meet high voltage, low current device test conditions requirement, also meet low voltage, high current device test conditions requirement, with a wide scope of application, is ideal test equipment for power department, repair engineering units and high voltage testing department.
Features
1. Smaller size, lighter weight compared with same voltage level, same capacity reactor.
2. Small temperature rise at rated load. Dry type epoxy cast, high mechanical strength, good insulation, nice and reliable;
3. Large capacity margin for frequency control source. Strong protection, good stability. with multiple working mode, easy to operate;
4. with 220V or 380V single phase power, convenient for onsite power sourcing;
5. Flexible configuration. Different type reactors for optional, can meet different test object requirements. Multifunctional, cost effective;
6. imported SPWM digital waveform generated chip. 16 digit frequency resolution. Frequency fineness up to 0.1Hz at frequency of 20-300Hz;
7. Orthogonal non-synchronous fix type carrier modulation mode, ensure good output waveform for the entire frequency range.
8. Advanced IPM module, ensure stability and security of apparatus;
