50kV VLF AC High Voltage Test Set Ultra Low Frequency Generator

Table 1

II.Features

The product has features as follows:

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

Overvoltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself, the actuation time is less than 20ms.

Overcurrent 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 low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.

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