OIT-14

Surge Impedance Meter

OIT-14

  • Measuring instrument for transient grounding impedance

Features

・This product can measure transient grounding impedance (Effective surge impedance ) , but a ground resistance tester cannot measure it.
・This product can measure transient grounding impedance without removing the overhead ground wire of the transmission tower.
・Small, lightweight, easy to operate
・Operation check with the test resistor
