Product Overview
Ultra-high-voltage equipment demands impulse test systems with both high voltage capability and precise waveform control. This 800 kV lightning impulse voltage generator is configured for UHV-class GIS, bushings, and surge arresters. The Marx circuit uses low-inductance capacitors and a resistive-filtered return path to maintain standard 1.2/50 μs waveforms under the high-capacitance loads typical of UHV GIS testing. The charging system provides constant-current control with ≤±1% voltage stability.
Test Functions
Lightning impulse voltage (1.2/50 μs) up to 800 kV
Switching impulse (250/2500 μs) with optional wave-shaping module
Chopped impulse with triggered gap
Full digital measurement with automated report generation
Use Scenarios
UHV GIS factory routine and type tests
UHV transformer insulation verification
Surge arrester residual voltage testing at elevated voltages
High-voltage research laboratory acceptance testing
Customer Pain Points Addressed
Waveform distortion at UHV capacitance levels: The low-inductance design and resistive filtering maintain front time within tolerance even with GIS load capacitance exceeding 10 nF.
Charging time limits throughput: Constant-current charging with 30–180 s programmable time completes a full charge cycle in under 3 minutes for most UHV loads.
Safety concerns at 800 kV: The system includes automatic grounding, discharge rod interlock, and door interlocks for the test bay.
FAQ
Q: What is the required floor space?
A: The generator body and divider require approximately 6 m × 4 m of clear floor area, plus a control room or shielded control console location.
Q: Can this system be used for switching impulse tests?
A: Yes, with the optional switching impulse module. The same capacitor bank is reconfigured via the wave-shaping resistors.
Q: What is the typical delivery lead time?
A: Standard configurations ship within 12–16 weeks from order confirmation, including factory acceptance testing.
