Product Description
Overview：
Loss Tester Intelligent Tg Dielectric Meter is a kind of instrument with high precision fully automatic measuring the dielectric loss tangent and capacitance of various high voltage electrical equipments in the power plants and substations. The adoption of frequency conversion technology could ensure the accurate measurement in the interference of strong electric field.
Main technical parameters：
1.High voltage output: 0.5~10kV
Increasing by 500V for each level, a total of 20 levels, capacity: 1500VA
2. Accuracy: tgδ: ± (reading *1.5% +0.06%)
Cx: ± (reading * 1.5% +5 PF)
3. Resolution: tgδ: 0.001% Cx: 0.001pF
4. Measuring range: 0.001% Internal high pressure : 3PF ～60000PF/10KV 60PF～1μF/0.5KV External high pressure: 3PF ～1.5μF/10KV 60PF～30μF/0.5KV 5.Power supply: AC 220V ± 10% 50/60 ± 1Hz 6. Measuring method: a.single frequency: 45(45Hz measuring)、50(50Hz measuring)、55(55Hz measuring)、60(60Hz measuring)、65(65Hz measuring) b.different frequency: 50D(45Hz/55Hz measure each time) 60D(55Hz/65Hz measure each time) Automatic frequency conversion 7. Harmonic adaptation: ≤ 3% 8. Application condition: -15 ℃－50 ℃ Relative humidity <80% 9. Dimension: 460 (L) × 345 (W) × 345 (H) 10. Weight: 35 kg Precautions： 1.The instrument is only used on power-off equipment. The grounding terminal should be connected to the grounding network reliably. 2.The instrument should be used in spacious, safe and reliable place. 3.The equipment under test is shifted to the maintenance state if the high-voltage lead is disconnected from operation state and could be cleaned. 4.The instrument could be tested only after good initial insulation test so as to avoid the poor insulation of equipment under test causing the damage of the instrument during the pressing process.
