Product Description

30kV-80kV Very Low Frequency Hipot Tester Vlf Dielectric Test Sets

Description

The Very Low Frequency (VLF) AC Hipot Tester is an advanced electrical testing equipment that is used to verify the insulation strength of high voltage cables, transformers, and other electrical apparatus. This tester applies a very low frequency alternating current (VLF) waveform to the device under test, which simulates the effects of an AC voltage stress on the insulation system.

Features

• VLF AC hipot testers are capable of generating voltages up to 200 kV RMS, with a frequency range typically between 0.1 Hz and 0.01 Hz.
• The waveform generated by this tester is essentially a sine wave, which closely simulates the AC voltage stresses experienced by most electrical device insulation systems.
• The VLF AC hipot tester is designed to provide precision measurement capabilities, with a wide range of selectable output voltages and current limits.
• Additionally, these testers incorporate advanced safety features, such as automatic voltage ramp-up and ramp-down, over-current and over-voltage protection, and user-configurable safety interlocks.
• These testers are also equipped with high-resolution displays and intuitive user interfaces that make it easy to set up and execute tests quickly and accurately.

Applications

The VLF AC Hipot Tester is a highly versatile instrument that can be used for a variety of applications, including:
 

• Testing of high voltage power cables
• Testing of transformers and switchgear
• Testing of motors and generators
• Testing of capacitors and reactors
• Research and development of new electrical products

 

Caution
To use this instrument, an AC power supply of 220V/50Hz with a frequency stability of less than 0.5% is required. The capacitance of the sample being tested should not exceed the instrument's rated capacity, as this could affect the output waveform. If the capacitance is less than 0.05µF, the instrument cannot output normally. Boosting voltage without a load or connecting to a resistive load is strictly prohibited when using this instrument.
