1、 Overview
The high current input unit adopts the latest structure, which is very suitable for partial discharge test of transformer and other products, and is used for measuring impedance of partial discharge tester. The input unit has built-in high-density magnetic core, which is not saturated, has good linearity and strong flow capacity, and has a magnet which can be adsorbed on the surface of the oil tank.
