The AC Resonant Test Set is specifically designed for AC withstand voltage testing of cross - linked cables, hydro generators, main transformers, busbars, GIS, and other electrical equipment. It is widely used by high - voltage testing departments at municipal, city, and county levels, as well as power installation and maintenance units, to evaluate the insulation performance of these devices under high voltage. By leveraging resonance between reactors and the test object's capacitance, the system generates high voltage for on - site or lab - based testing across diverse electrical equipment.
High Efficiency & Energy Saving: Operates by supplying only the active power consumed by the system, significantly reducing required power capacity.
Portability: Lightweight design (max. single unit weight ≤40kg) for easy transportation and field deployment.
Superior Waveform: Pure sine wave output with ≤1.0% waveform distortion, ensuring high - quality test signals.
Enhanced Safety: Multiple protections including overvoltage, overcurrent, zero - start, detuning protection, and flashover protection to prevent accidental breakdown of test objects.
User - Friendly Operation: Supports automatic tuning + manual voltage adjustment modes with a full touchscreen interface for intuitive parameter setup and real - time monitoring.
Data Management: Enables data storage, local/remote printing, and post - test analysis.
Temperature: -10°C to +40°C
Humidity: ≤85% RH
Altitude: ≤1000m (derating required for higher altitudes)
Environment: Free of conductive dust, explosive gases, and corrosive substances.
Warranty: 3 - month replacement policy, 1 - year free repair, and lifelong paid maintenance post - warranty.
Safety Note: Avoid contact with live terminals; ensure proper grounding for personnel safety.
Components: Includes variable - frequency control power supply, excitation transformer, reactors, capacitive dividers, and optional compensation capacitors.
Q: Fan fails to start.
A: Check for emergency stop activation, fault protection triggers, or thermal overload. Reset faults or allow cooling before restarting. Contact the manufacturer if unresolved.
Q: Auto - tuning fails to find resonance.
A: Verify proper grounding, inspect all connections (excitation transformer, reactor, divider cables), and check for open circuits.
Q: Unable to reach target test voltage.
A: Possible mismatched reactor/test object capacitance, low Q - value due to high losses, insufficient excitation voltage, or improper high - voltage wiring. Adjust parameters, enhance excitation, or optimize wiring.
