Earth grounding is vital to protect our life and electrical facilities. It helps eliminate losses due to faulty installation and reduces damage from lightning strikes and induced voltages. It covers and improves the performance of our electrical equipment and home appliances. Over time, ground systems can degrade or become ineffective. Corrosion and weather influences exert mechanical strain on ground rods and cause metallic corrosion. Catastrophic events like lightning strikes or large fault currents can cause instant degradation to our systems. The risks from ground system deterioration may lead to severe electrical shock, equipment damage, disruption in the performance of sensitive equipment and heat build-up on issues. Keeping an adequate low resistance ground connection is essential to the protection and performance of our electrical system. To practise earth resistance testing should be regularly on installation and preventive service. In addition, soil resistivity tests can be used in prospecting, locating, and designing new grounding electrodes and systems. It can help make healthy environmental conditions and create different ground system needs. BST's new ER-80 series 4-terminal ground testing instrument includes two models with automatic and manual operation testing flexibility. Both models (ER-80A and ER-80M) employ measuring functions for ART (Attached Rod Technique) testing capabilities. The basic kit includes the test leads, connectors/adapters, and a rugged carry case – everything you need to start testing in one package.
