About This Product
■Features
1.Measures transient ground resistance values (effective surge impedance) that cannot be measured with a ground resistance meter
The transient ground resistance value (effective surge impedance) caused by lightning surges, etc. differs from the steady ground resistance value due to the effects of reactance and capacitance contained in the ground. It is important to use a surge impedance meter to measure grounding poles where lightning surge current flows, such as lightning protection equipment, power transmission towers, and communication antenna tower legs.
2.Measurement can be performed without removing the overhead ground wire of the transmission tower
3.Small and lightweight, easy to operate
4.Operation check using test resistance
You can perform a simple operation check to confirm whether this product can measure normally.
