1. High precision
Using precision high-voltage film capacitors and precision high-voltage glass glaze resistors, high input impedance, reduced test current, low power consumption, and improved measurement accuracy and stability of the instrument; the signal processing part uses high-performance OP for signal amplification and double integration Type AD sampling technology, four-and-a-half-digit liquid crystal display, with a maximum resolution of 0.001kV.
2. Good anti-interference performance
Adopt special shielding technology. The surface of the pressure equalizing ball of aluminum alloy material is smooth and shiny, which effectively improves the electric field distribution around the equalizing ball, prevents sharp discharges, and improves the anti-interference ability of the measurement data. Low-voltage display instrument adopts full gold
It is a closed structure and shielded. The high-voltage divider and the low-voltage display meter are connected by high-quality coaxial cables to reduce the impact of high voltage on the display value, so as to achieve high stability and high linearity
3. Safe and reliable
This instrument is composed of a high-voltage divider and a low-voltage display instrument. The high-voltage divider adopts American DuPont filling materials and is potted with a special process. It has a smaller structure, lighter weight, low internal partial discharge and high reliability. There is no oil leakage problem. The high-voltage divider and the low-voltage instrument are connected by coaxial cable when working, and the distance between the high and low voltage parts is relatively long, and the work is safe and reliable.
