The VLF AC Cable hipot tester adopts digital frequency conversion technology, single-chip microcomputer control, voltage boost, buck, measurement, protection completely automatic. Due to the full electronic, so small size and light weight, the use of large screen color touch display, clear and intuitive, simple operation, display output waveform. The design index conforms to the national standard of "General Technical Conditions of Ultra-low frequency high voltage generator".
Product features for this type of VLF hipot tester:
Rated voltage | Carring capacity | Application range |
30kV(peak) | Automatic frequency change:0.1Hz-0.01Hz On-load capacity:<=10µF | Used for voltage test of cables and motors within 10KV |
40kV(peak) | Automatic frequency change:0.1Hz-0.01Hz On-load capacity:<=10µF | Used for voltage test of cables and motors within 10KV |
50kV(peak) | Automatic change frequency: 0.1Hz-0.01Hz Load capacity: <=6µF | Used for voltage test of cables and motors within 15KV |
60kV(peak) | Automatic change frequency: 0.1Hz-0.01Hz Load capacity: <=5µF | Used for voltage test of cables and motors within 25KV |
80kV(peak) | Automatic change frequency: 0.1Hz-0.01Hz Carrying capacity: <=6µF(within 50kV), <=4µF(above 50kV) | Used for voltage resistance test of cables and motors within 35KV |
Output rated voltage | 30kV-80kV The different specifications are shown in above Table |
Output frequency | Automatic conversion range: 0.1Hz-0.01Hz |
Carrying capacity | See above Table |
AC voltage resolution | 0.1kV |
Voltage accuracy | 3% |
AC current resolution | 0.1mA |
AC current accuracy | 3% |
Voltage positive and negative peak error | ≤ 3% |
Voltage waveform distortion | ≤ 3% |
Conditions of use | indoor and outdoor; Temperature: -10ºC∽+40ºC; Humidity: ≤ 85%RH |
Input power | Frequency 50Hz, voltage 220V±5%(or frequency 60Hz, voltage 110V±5%). If the micro generator is used for power supply, the frequency conversion generator should be used, and the ordinary generator can not be used, because the ordinary generator speed is unstable, which will make the boost voltage abnormal and damage the instrument. |
Main structure of ultra-low frequency high voltage power supply(VLF hipot tester)
For the VLF hipot tester with a rated voltage below 50kv, a booster is used, which is called the single-coupled ultra-low frequency, and its structure and components are described in the following figure:
