1. Frequency anti interference 2. Testing CVT need not change wire 3. It can est the turn radio of CVT
| Product Information: |
| Eliminating 50HZ interference by frequency conversion as working, can get reliable data even in strong electromagnetism interference site.Using integration construction, with standard capacitance and high-voltage power supply in it, which is easy for testing work and reducing line connection in site.With CVT test function which can realize self-active test without any extra attachment.Grounding test in true reverse, with minor capacity ground test which can get precise result.With protection of over current, the instrument would be protected well as grounding test medium was breakdown or short circuit.With protection of grounding, the instrument would not out put high voltage if the instrument was not grounding well.Apply range: Suitable for power station, substation, and the factory with high automatic level or with more CVT. Technology specification: 1.Range: a. Capacitance value: Can reached to 4pF-50 nF range in standard mode, can continuously monitoring and not limited to time. In intermittent operation mode, meant measuring at a time not exceed by 15 minutes, can measure 60nF, and design of instrument can satisfied for short-time over range.b. Dielectric dissipation factor: 0~100% 2. Precision: a. Capacitance precision: ±0.5% ·Reading ±2pF (UST mode) UST: Ungrounded specimen test. ±0.5% ·Reading ±6pF (GST mode) GST: Grounded specimen test. b. Dielectric dissipation factor precision: ±1%·Reading ±0.05% (UST mode) ±1%·Reading ±0.05% (GST mode) (cx>500PF) ±2%·Reading ±0.2% (GST mode) (cx≤500pF) 3.Resolution: Capacitance resolution: Min, resolution 0.01pF Dielectric dissipation factor resolution: Min, resolution 0.01% 4.High-voltage power: 1000VA, 0~10KV continuous setting. 5.Working environment: working power: AC220V±10%, 50HZ working temperature: 0~40°C.
