Overview

Static high-voltage meters are based on electrostatic forces. When a voltage is applied between two specific electrodes, the electrodes will be subjected to an electrostatic force f, which has a fixed relationship with the value of the voltage u. The magnitude of the applied voltage u can be determined by measuring the size of f or the displacement or deflection of the movable electrode caused by it.

Product Details

An electrostatic voltmeter is a meter or device that uses the principle of electrostatic forces to measure steady-state voltage. The SGB-C series consists of two parts: a low voltage display meter and a high voltage divider, which are connected by matching cables.

The electrostatic voltmeter produced by our company is an ideal choice for high voltage measurement tests. The instrument is mainly used for measuring DC high voltage and AC high voltage in power systems and electrical and electronic equipment manufacturing departments.

Product features

1. High precision. The use of precision high-voltage thin film capacitors and precision high-voltage glass glaze resistors results in high input impedance, reduced test current, low power consumption, and improved measurement accuracy and stability of the instrument; The signal processing part adopts high-performance OP for signal amplification, uses double integral fraction AD sampling technology, four and a half bit LCD display, with a resolution of 0.001kV, and is an updated product of high-voltage electrostatic voltmeter.

2. Good anti-interference performance. Adopting special shielding technology. The surface of the uniform pressure ball made of aluminum alloy material is smooth and shiny, effectively improving the electric field distribution around the uniform pressure ball, preventing discharge, and enhancing the resistance of measurement data. The low voltage display instrument adopts a fully metal enclosed structure shielding, and the high voltage divider and low voltage display meter are connected by high-quality coaxial cables to reduce the influence of high voltage on the indication, thereby achieving high stability and high linearity.

3. Safe and reliable. The AC/DC voltage divider is composed of a high voltage divider and a low voltage display instrument. The high voltage divider is filled with DuPont filling material from the United States, sealed with special technology, has a smaller structure, lighter weight, and reduces internal partial discharge, resulting in higher reliability. There is no oil leakage issue. The high voltage divider and low voltage instrument are connected by coaxial cables during operation, and the distance between the high and low voltage parts is relatively far, ensuring safe and reliable operation.

4. Easy to operate. Using a dip switch to switch between high and low voltage, AC and DC, convenient and fast. The four and a half digit LCD directly displays the measurement results, which is simple and intuitive. Bringing great convenience to on-site inspection work.

5. Easy to carry. Adopting a portable structure, the whole machine uses an aluminum alloy packaging box as the chassis, which can be easily disassembled and assembled. Small size, light weight, easy to carry, and very convenient to use.
