Huazheng HZHG-JQ-100 AC HV High Voltage Divider

Overview

The AC voltage divider is mainly used for measuring AC high voltage. The device consists of a high-stability "non-inductive resistor" voltage divider and a high-precision digital sampling system. The meter is equipped with a rechargeable battery that can work continuously for more than 4 hours. The voltage divider, LCD digital display head, measurement line, power line, etc. are concentrated in an aluminum alloy box, which is easy to carry and use. The AC voltage divider is suitable for on-site measurement of power systems and for measuring power frequency AC or resonant AC voltage in laboratories of colleges and universities.

Work Principle

The AC voltage divider is a resistor voltage divider, which consists of two parts: the AC voltage divider and the kilovoltmeter. The resistor voltage divider is composed of low temperature drift resistors. It uses a 32-bit ARM chip plus a true color touch screen.

The kilovoltmeter has the following technical features:

1. The high voltage is sampled by the voltage divider and connected to the kilovoltmeter through a coaxial cable. The kilovoltmeter automatically identifies the input AC voltage

2. When measuring AC, the true effective value of the measured voltage can be displayed on the display screen of the meter;

3. The instrument adopts a true color touch screen human-machine interface, which is easy to operate and has high measurement accuracy. The power supply can be either an external power supply (charger) or a built-in lithium battery DC power supply, which is convenient for on-site use in various occasions.
