产品介绍
DAC-LAS-2 is for measuring the resistive leak current of a zinc oxide surge arrestor (gapless) at the ground wire.
In general, the leak current of a surge arrestor is the combination of a resistive current, in phase with the applied voltage, and a capacitive current, in 90-degree lead. Especially the resistive current is said to be an important factor for detecting the deterioration of surge arrestors.. By simply clamping around the ground wire of the arrestor with the jaw of the current clamp CT, the set detects the leak current and can measure only the resistive current separated from the leak current.
