Capacitance and Tan Delta (Dissipation Factor) Measurement System
- High-voltage AC injection up to 12 kV RMS for field and lab insulation testing.
- Measure tan delta / power factor and capacitance with high accuracy (tan delta ±0.005%, capacitance ±0.05%).
- Dielectric Frequency Response (NB DFR) sweep 1–500 Hz for deeper insulation assessment beyond line-frequency DF.
- Modular device architecture, allowing flexible configuration and easy maintenance.
- Web-based software with Wi‑Fi support for fast test setup, guided wiring diagrams, and report-ready results.
Stand-Alone Testing Device Designed for Quick Setup and Immediate Dielectric Health Assessment.
CAPTAN 12
All you need for on site high voltage insulation testing
CAPTAN 12 supports classic line-frequency (50 or 60 Hz) dissipation factor testing and frequency-sweep diagnostics (1–500 Hz) to evaluate insulation condition on high-voltage equipment.
Built on a modular hardware architecture
CAPTAN 12 is designed for quick servicing and long-term maintainability. Individual modules can be replaced independently, reducing downtime and simplifying repairs. This approach also makes upgrades more practical as your testing needs evolve.
