Product Description

VLF 33kV Cable Testing 0.01Hz 30kV to 80kV AC Hipot Tester

Product Description

VLF 33kV Cable Testing 0.01Hz 30kV to 80kV AC Hipot Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.

The very low frequency withstand voltage test is essentially an alternative to the power frequency withstand voltage test. It is much smaller, lighter, and portable than a power frequency withstand voltage tester. It is proven at home and abroad that a 0.1Hz ultra-low frequency withstand voltage test can replace a power frequency withstand voltage test.

It can be applied to 10kV, 35kV, 300MW thermal power machines, 10kV, 35kV power transformers, and other electrical equipment.

Features

Data of current, voltage, and waveform can be directly sampled at the high voltage side, so the data is real and accurate.

Over-voltage protection: If the output exceeds the set limit of voltage, the instrument will shut down to protect itself; the actuation time is less than 15ms.

Over-current protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on the low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time is both less than 15ms.

A high voltage output protective resistor is provided in the voltage boost body in the design, and this eliminates the need for an additional protective resistor connected outside.

As a result of a high and low voltage closed-loop negative feedback control circuit, the output is without a capacitive rise effect.

The high-voltage control part adopts an innovative light control HV switching unit, and the control is accurate, safe, and reliable.

With a color man-machine interface, touch control, plus controls modular software operating system, precise and intuitive.

Multi-purpose, can simultaneously measure the capacitance, insulation resistance, leakage current, and AC withstand voltage test.
