[0002] The two-wire DC ultra-wide voltage sensor is a sensor used to measure extremely high voltages in DC systems. It has two power line connections and is often used to measure DC systems where voltages are beyond the traditional measurement range. The two-wire DC ultra-wide voltage sensor uses principles such as electric field effect or Hall effect to convert high voltage signals into measurable voltage signals. Its internal circuit reduces the voltage signal to an acceptable measurement range so that it can be connected to the measurement device.

The spacing between the voltage sensors can only be adjusted by manual pushing and pulling, which poses a risk of electric shock. In addition, they lack fixation and are prone to shaking under the action of the electromagnetic field during use, affecting stability. Utility Model Content
