VLF Hipot Tester HZG1701
The HZG1701 VLF Hipot Tester (Very Low Frequency High Voltage
Generator) is a professional AC withstand voltage test system
designed for insulation testing of high-voltage electrical
equipment.
The equipment uses 0.1Hz ultra-low frequency AC withstand voltage
technology, which reduces the required test power capacity while
maintaining effective insulation stress on the equipment under
test. Compared with traditional power-frequency AC withstand
voltage systems, VLF technology offers a more compact and
field-practical solution.
The HZG1701 is especially suited to high-capacitance loads such as
power cables, motors, generators, and power capacitors, combining
digital frequency-conversion control, high-speed data acquisition,
and multiple protection functions for safe and accurate insulation
testing. Output voltage can be customized to match the customer's
specific test requirements.

Key Features
0.1Hz Ultra-Low Frequency Technology
Replaces traditional power-frequency withstand testing for
large-capacitance loads, reducing the required power capacity while
keeping effective insulation stress on the test object.
Compact Design for Field Testing
Smaller and lighter than traditional AC withstand test sets,
simplifying transport, setup, and outdoor testing.
Automatic Test Control
Integrates automatic voltage boosting, voltage/current monitoring,
data recording, and protection control into one automated sequence.
Multiple Safety Protections
Overvoltage protection, overcurrent protection, automatic shutdown,
and automatic discharge.
Touch Screen Operation
7-inch touchscreen for setting parameters, monitoring output,
viewing waveforms, saving records, and printing reports.
Stable Output Performance
High-voltage closed-loop feedback keeps waveform distortion low and
voltage output stable through the test.

FAQ
What is a VLF Hipot Tester used for?
It's used for AC withstand voltage testing of power cables, motors,
generators, and other high-voltage electrical equipment to evaluate
insulation performance.
Why use 0.1Hz ultra-low frequency testing?
It reduces the required power capacity compared with
power-frequency testing, making the equipment smaller and more
practical for field use.
Can the output voltage be customized?
Yes. The HZG1701 can be configured to a specific output voltage
based on your test requirements.
Can the HZG1701 be used outdoors?
Yes — its compact structure and reliable design suit outdoor
testing at substations, cable projects, and maintenance sites.
