| Packaging Details: | standard package for 0.1hZ AC high voltage vlf cable testing hipot tester with tan delta measuring & partial discharge |
| Delivery Detail: | vlf ac hipot tester 7-15days after order confirmed |
1) single connection structure (one booster) shall be adopted for ultra-low frequency with rated voltage less than or equal to 50kV; The ultra-low frequency greater than 50kV adopts series structure (two boosters are connected in series), which greatly reduces the overall weight and enhances the load capacity. Moreover, both boosters can be used alone to achieve multi-purpose of one machine.
3)Current and voltage data are directly sampled from the high voltage side, so the data is accurate.
4)Intelligent comprehensive protection function: there is no need to set the current and voltage protection value. The instrument can calculate the overvoltage and overcurrent protection value according to the capacitance of the test object and the test voltage value. It can also protect the sudden change of voltage and current, so it can capture the discharge. The protection action time is less than 20ms.
5)High voltage cable 150KV is adopted for output, which is safe and reliable.
6) Since the closed-loop negative feedback control circuit is adopted, the output has no capacity rise effect.
7) Dielectric loss(tgδ) measurement function (for buyer's option), which can measure the dielectric loss, capacitance and insulation resistance of the test object at the same time.
1) Rated output voltage: 30kv-80kv, details see Table 1
2)Output frequency: automatic frequency conversion, range: 0.1Hz-0.01Hz
3)carrying capacity: see Table 1
4)Measurement accuracy: ≤ 3%
5)Voltage positive and negative peak error: ≤ 3%
6)Voltage waveform distortion: ≤ 3%
7)Operating conditions: indoor and outdoor; Temperature: - 10 ºC - + 40 ºC;
Humidity: ≤ 85% RH
8) Input power supply: 220V ± 5%, 50Hz/60Hz. If the micro generator is used for power supply, the frequency conversion generator shall be used instead of the ordinary generator, because the unstable speed of the ordinary generator will make the boost abnormal and damage the instrument.
