Tan Delta-Power Factor Tester

Capacitance and Dielectric Loss Measurement:

• Frequency Conversion Anti-Interference: Advanced frequency conversion technology enables stable, precise measurements even under 200% interference, ideal for on-site testing.
• High-Precision Measurement: Utilizes digital waveform analysis, bridge self-calibration, and high-precision standard capacitors for accurate dielectric loss measurement. Consistent accuracy for forward/reverse wiring and reduced test line capacitance interference.
• Versatile Input Options: External connections for oil cup and solid material electrodes allow dielectric loss testing on insulating oils and solid insulators.

Exceptional Compatibility:

• Automatically detects 50Hz/60Hz systems and supports generator power, adapting to fluctuating frequencies for seamless testing.
• Includes built-in series and parallel dielectric loss models, fully compatible with calibration benches, ensuring streamlined instrument verification.

Robust Multi-Level Safety Protections:

• High-Voltage Protection: Responds instantly to short circuits, breakdowns, or high-voltage current fluctuations, cutting off output in high-risk scenarios.
• Low-Voltage Protection: Safeguards against power surges, incorrect connections, power failures, and overvoltages.
• Grounding Protection: Activates if grounding is insufficient and dangerous voltage is detected on the casing.
• CVT Safeguards: Comprehensive high/low voltage protection limits ensure safety during CVT measurements, with no high-voltage output when inappropriate.
• Anti-Misoperation: Features a dual power switch, real-time voltage and current monitoring, multiple key confirmations, clear terminal markings, and controlled voltage adjustments with sound and light alerts.
• Anti-Capacity Rise: Automatically stabilizes voltage during large-capacity tests to counter “capacity rise” effects.
• Anti-Seismic Design: Durable, shock-resistant build withstands vibrations and bumps during transport without damage.
• High-Voltage Cable: Includes floor-compatible high-voltage insulated cables for added versatility.
