- Rated capacitance: 500pf rated electrical resistance: 1000M

- Rated AC voltage: 500kV rated DC voltage: 500kV

- Nominal AC partial voltage ratio: 2000 / 1 nominal DC partial voltage ratio: 10000 / 1

- Running time: long time

- The Dielectric loss: < 0.2% AC / DC voltage divider picture

- Temperature coefficient: < 0.0004

- Overvoltage capacity: the overvoltage shall not cause any insulation damage of the test transformer under the condition of 110% uh for 60s;

- Measurement accuracy AC: <± 1% measurement accuracy DC: <± 0.5%

- Running time: long

- Top pressure equalizing cover structure: the pressure equalizing cover is made of high-quality LY2 pure aluminum plate, and the welding process adopts sub arc welding machine to ensure that aluminum oxidation does not occur when placed in the air for a long time. Its radius of curvature contains 550kV power frequency voltage, and corona does not occur on the pressure equalizing cover. In particular, the parts arranged above require hot-dip galvanizing after metal processing to prevent iron oxidation in the air, Over a long period of time, the above components will be oxidized, resulting in corona discharge.

- Volume: φ250/φ850×2600㎜

- Weight: < 250kg
