The KDZD is a horizontal-type sphere gap discharger, a core device for high-voltage electrical tests. It consists of a movable base, insulating support tubes, copper spheres, an adjusting scale, and a water resistor. With a built-in 1Ω per volt protection resistor, it is connected in parallel with test samples to measure spark discharge voltages and provide overvoltage protection. It supports voltage correction for atmospheric conditions (temperature and pressure) using the formula V'2 = S×V2, ensuring accurate results across diverse environments. Available in multiple voltage ratings (50kV to 1500kV), it is a portable, reliable tool for high-voltage labs and power system testing.
