Technical Parameters

Features

Intelligent PLC Control: Utilizes advanced human-machine interfaces (HMI) and touch-screen panels for programmable, automated testing.

Automated Features: System units often feature automated polarity switching and continuous charging modes for efficient batch testing.

Safety Mechanisms: Built-in safeguards include emergency stop buttons, gate interlocks, visual/audible alarms, and protective grounding devices to ensure operator and equipment safety.

Low-Inductance Design: Compact, space-saving capacitor banks and low-inductance wave-shaping resistors prevent current distortion and accommodate steep impulse conditions.

Precise Measurement: Integrates high-speed oscilloscopes (like Tektronix) and precision current monitors to accurately capture, analyze, and report peak current and voltage data.

Maintenance Information

Regular inspections ensure that your impulse generator consistently meets required energy and waveform standards.

Capacitor Banks: Visually inspect high-voltage capacitors for leaks, swelling, or corrosion. Verify capacitance and equivalent series resistance (ESR) annually. Ensure auto-grounding switches operate properly to safely discharge residual energy before physical access is granted.

Spark Gaps: The waveform usually requires high-energy triggering or crow-bar circuits. Routinely check and clean the sphere or trigatron gaps. Pitting or accumulated residue from arcing can alter the breakdown voltage and distort the impulse rise-time.

Resistors & Inductors: Plug-in resistors shape the waveform. Check these components for signs of thermal stress, cracking, or changes in ohmic value. Loose connections cause parasitic inductance that ruins the pulse shape.

Charging Rectifier: Clean internal dust and inspect the high-voltage diodes for signs of degradation. Test the voltage regulation to ensure it stabilizes at the required charging voltages.

Control & Trigger System: Verify that safety interlocks, emergency stops, and relays are fully functional.
