The Partial Discharge - Free Inductive Resonant Test System is a high - performance testing device designed for AC withstand voltage tests and partial discharge (PD) tests on electrical equipment. By leveraging an excitation transformer to activate the resonant circuit, it generates the required test voltage through resonance between the reactor inductance (L) and the test object capacitance (C) at preset frequencies. This system is ideal for capacitive equipment such as power transformers, instrument transformers, power cables, gas - insulated switchgear (GIS), circuit breakers, disconnectors, insulators, bushings, as well as large generator sets' power - frequency withstand voltage tests and grounding grid testing.
High - Quality Output: Pure sinusoidal waveform with distortion <3%, eliminating the need for peak measurement.
Enhanced Safety: Fiber - optic control technology ensures complete electrical isolation between high - and low - voltage circuits.
Portable Design: Compact and lightweight for easy transportation and on - site applications.
Efficient Operation: User - friendly interface improves work efficiency by about 50%.
Multi - Layer Protection: Built - in safeguards against overvoltage, short circuits, zero - position startup errors, and more.
Precision Performance: Frequency stability ≤0.01Hz, voltage instability <1%, ensuring reliable test results.
Flexible Modes: Supports manual/automatic voltage ramping and auto - tuning functions.
Equipped with a microprocessor - based control system and dedicated signal - generation chips, this system ensures exceptional stability and reliability. Its intelligent protection mechanisms prevent operational hazards, while dual operation modes (manual/automatic) adapt to diverse testing requirements.
Q: How to ensure long - term system stability?
A: Regularly inspect cooling systems for proper airflow, maintain a dust - free environment, and follow scheduled preventive maintenance per the manufacturer's guidelines.
Q: What to do in case of fault alerts?
A: Immediately halt testing, disconnect power, and refer to the troubleshooting guide. For unresolved issues, contact our technical support team.
Q: Key usage precautions?
A: Verify all connections before operation, strictly adhere to protocols, monitor parameters in real - time, and power down the system post - test for safety.
For detailed operation and maintenance instructions, always refer to the latest official user manual and technical documentation.
