40kv Vlf AND dc Hipot Tester AC Vlf Test Equipment for Breakdown Cable Detection Vlf High Voltage Tester 

A type of electrical testing equipment used primarily for the insulation testing of cables, transformers, motors, and other electrical systems.

 It is especially suitable for withstand voltage test of electrical equipment with large insulation equivalent capacitance (such as power cable, power capacitor, large and medium- sized generator and motor, etc.), which conforms to the national standard of electric power industry, general technical conditions.

Ⅰ: Key Features of a 40kV VLF & DC Hipot Tester: 

  • Testing Voltage: This tester can apply up to 40kV of voltage during either the DC or VLF test.

  • Insulation Resistance Measurement: Often integrated to measure the resistance of the insulation during the test, which can help assess the condition of the insulation.

  • Safety Features: These units typically have built-in safety features such as automatic discharge circuits, fault detection, and alarms to ensure safe operation during testing.

  • Portable Design: Many VLF & DC Hipot testers are designed to be portable and rugged for field use, which is essential when testing long cable runs or remote equipment.

  • Test Duration Control: The ability to set test durations (from a few seconds to several minutes) is common, especially in field scenarios where a quick test is required.


  • Ⅱ: Applications For The VLF Tester Using:

  • Test de câble: Ensures the insulation of power cables is intact and can handle the operational voltage.
    Substation Equipment: Tests the insulation of transformers, switchgear, and other high-voltage electrical components

    • Motors and Generators: Checks the insulation of large electrical motors and generators, ensuring their reliability.

    • Preventative Maintenance: Used for routine checks to detect early signs of insulation failure before they lead to downtime or more serious damage.
