A range of grounding, surge, and lightning-protection products for the wind-energy industry come from Erico,
Solon, Ohio. Company engineers provide design assistance for grounding and lightning protection for facilities worldwide. The company says it can design lightning protection that complies with any applicable standard using its Lightning Protection System Design software.
Also, the company manufacturers a range of Ground/Earth Resistance Testers. For example, the handheld Eritech EST101 can complete 2-pole resistance and 3-pole grounding resistance measurements as well as a ground-to-neutral impedance tests. The EST201 model adds a capability for performing 4-pole resistance measurements to determine soil resistivity. The Universal Earth System Tester EST301 provides the same measurement capabilities as the EST201 and adds capabilities for clamp-on selective and stakeless measurements.
And the latest EST401 clamp-on ground resistance tester measures ground rod and small-grid resistance without auxiliary ground rods. The 401 tester works with multi-grounded systems without disconnecting the ground under test. By performing measurements on intact ground systems, users can measure the resistance to ground and verify the continuity of the grounding connections and bonds. An electric current management function lets the unit measure ground current at pole ground rods, service entrances, pad-mounted transformers, transmission towers, and service panels.
