Highlights
Microsecond-to-nanosecond waveform capture for insulation diagnostics and power quality
For substation switching/lightning overvoltages, high-speed-rail transients, partial discharge pulses and power-quality disturbances. Wideband RC dividers, UHF antennas and high-frequency Rogowski coils combined with ≥10 MS/s synchronous acquisition capture transient waveforms from microseconds down to nanoseconds, enabling overvoltage front, PD spectrum and harmonic/flicker/sag analysis.
Extremely wide frequency span: from power frequency to lightning and nanosecond partial-discharge pulses spans more than ten orders of magnitude — no single band can cover it all.
High-potential, strong-EMI environment: substations and high-speed-rail traction networks carry hundreds of kilovolts and strong electromagnetic fields, demanding strict insulation, shielding and isolation.
Sporadic, non-repeatable transients: switching overvoltages, lightning overvoltages and partial discharges are occasional events, requiring long-term monitoring and reliable triggering to capture.
Multi-point time traceability: waveforms from different points must be aligned on a µs-level time base to invert propagation paths and locate faults.
