HZHG-F400KV-1.0 400kV AC DC Digital Kilovoltmeter
The HZHG-F400KV-1.0 AC/DC High Voltage Divider is a precision measurement system composed primarily of two key components: a capacitor-resistor high-voltage divider and a high-precision digital voltmeter.
The system is designed for measuring both AC and DC high voltages, delivering accurate and reliable results across a wide measurement range. Its robust construction and precision design make it particularly well-suited for on-site measurements in power systems, where dependable high-voltage measurement is essential.

Range Switching
The voltage measuring meter features two selectable measurement ranges, which can be switched by pressing the range switching key.
High Range – When the high range is selected, the voltage measurement range extends from zero to the rated voltage value, allowing full-scale measurement capability.
Low Range – When the low range is selected, the voltage measurement range is limited to 0 to 200 kV, providing finer resolution for lower voltage measurements.
