This product is designed for AC and DC withstand voltage tests on large-capacitance test items such as cables and motors. It is not suitable for small-capacitance or resistive test items such as zinc oxide arresters.
Product features for this type of VLF cable 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 |

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. |
