The UHV-615 SF6 density relay tester is an intelligent calibration instrument for SF6 density relays. Core components are imported to ensure high integration, measurement precision, repeatability and field reliability.
Overview / Intended use- Intended use: calibration and on-site testing of SF6 density relays and associated SF6 gas equipment.
- Design: compact integrated case, portable and easy to carry; key parts use imported components to ensure measurement accuracy.
Features- Strong anti-interference capability: electric-field induction immunity up to 2 mA (50/60 Hz), enabling reliable on-site measurements in high-voltage substations.
- High short-circuit current: typical short-circuit current 10 mA, suitable for testing large-capacity and high-inductance components.
- Wide resistance measurement range with high resolution for precise readings.
- Selectable high-voltage output levels with smooth adjustment from 0 V up to the selected voltage (0.1–5 kV).
- Acousto-optic reminders and timing functions to assist absorption ratio and polarization index recording.
- Durable, wear-resistant external materials and a robust integrated housing for field use.
Technical specifications (selected)- Output voltage levels (selectable): 0.1 kV, 0.25 kV, 0.5 kV, 1 kV, 2.5 kV, 5 kV.
- Test voltage accuracy: ±(5% + 10 V).
- Short-circuit current: typical 10 mA.
Range and accuracy (resistance measurement)- 20 MΩ (range 0.01 – 19.99 MΩ) — accuracy ±(5% + 3 d).
- 200 MΩ (range 5.0 – 199.9 MΩ) — accuracy ±(5% + 3 d).
- 2000 MΩ (range 50 – 1999 MΩ) — accuracy ±(5% + 3 d).
- 20 GΩ (range 0.5 – 19.99 GΩ) — accuracy ±(5% + 3 d).
- 200 GΩ (range 5.0 – 199.9 GΩ) — accuracy ±(10% + 3 d).
- 2000 GΩ (range 50 – 1999 GΩ) — accuracy ±(20% + 10 d).
Basic parameters- Anti electric-field interference ability: 2 mA (50/60 Hz).
