1. Introduction

ETCR5500 Series Earth Resistance Test Sensor breaks traditional test mode. It adopts non-touch clamp test, which is widely applied to earth resistance test for electrical equipment in the industries of power, telecommunication, meteorology, oil field, construction and manufacturing. The latest magnetic shielding technology and CT technology can ensure high accuracy, reliability and stability of non-stop test.

ETCR5500 Series Earth Resistance Test Sensor can be divided into open-loop clamp structure and closed-loop clamp structure, and also into long jaw type and round jaw type. Long jaw is especially suitable for flat steel earthing, and can meet test requirements for different earthing systems. For circuit earthing system, there is no need for cutting of down-conductor lead or for auxiliary electrode, safe and time saving.
