Product Overview & Application
The AC Resonant Test System with PD (Partial Discharge) is a high - performance testing device developed by Wuhan Goldhome Hipot Electrical Co., Ltd for high - voltage electrical equipment in power systems. It is designed for AC withstand voltage tests and partial discharge detection, utilizing variable - frequency power supply to achieve resonance between inductance (L) and capacitance (C), thereby applying high voltage to test samples.
Features & Advantages
- Enhanced Safety: Multiple protections (over - voltage, over - current, breakdown) for operator and equipment safety.
- User - Friendly Design: Simplified wiring and microcomputer - controlled system ensure stable, intuitive operation.
- Portability: Compact structure for easy transportation and on - site testing.
- Low Distortion: Output sine wave distortion <1% for non - destructive testing.
- Energy Efficiency: High output power with low input requirements, ideal for limited power supply scenarios.
- Data Management: Data storage, query, and print functions for analysis and reporting.
- Flexible Modes: Supports single/three - phase switching and parallel operation for diverse testing needs.
- Self - Healing Capability: Automatic repair of partial amplifier tube failures.
Operating Conditions
- Altitude: ≤3000m
- Temperature: - 10℃ to 40℃
- Humidity: ≤95% (at 25℃)
- Storage Temperature: - 20℃~50℃
- Humidity: ≤95%
- Environment: Free of conductive dust, explosive hazards, corrosive gases; reliable grounding; tilt ≤5°.
Maintenance & Troubleshooting
Routine Maintenance:
Regularly inspect wiring and tighten connections.
Keep the device clean and dry to prevent dust accumulation.
Secure equipment during transport with dedicated straps.
Discharge capacitors fully before servicing.
Common Issues & Solutions:
- Power Indicator Off: Check if the circuit breaker is closed or press the panel's power button.
- Control Interface Failure: Ensure power and communication links (fiber/wireless) are active; reboot.
- Tripped Circuit Breaker: Disconnect output filter 1P breaker; use non - leakage - protected breakers.
- HV Measurement Box Setup: Turn off measurement switches in the calibration interface, save settings, and restart.
- "Overload Protection" Alert: Reduce excitation transformer ratio (adjust taps) to minimize losses.
