Earth Resistance Testers

Used to measure the earth resistance in power substations, industries, distribution networks, transmission towers/electrical pylons.


Perform earth resistance measurements of simple or complex electrode systems, ground resistivity measurements (4-wire Wenner‘s principle), and spurious voltage measurements according to IEC 61557-5.

The equipment injects an electronically generated current in the soil. Both current and voltage developed are measured with high precision.

Ground Jumper Tester

Perform in-service testing of temporary grounding jumper assemblies used on de-energized electric power lines and equipment as specified by ASTM Standard 2249-20E01.

Model JT-200 Ground Jumper Tester is equipped with separate voltage sensing leads to avoid problems related to contact resistance between the test set and jumper under test.
