Page 16: Field Applications
Field Applications This ground resistance clamp meter is designed to test the ground resistance of any loop system. In addition to measuring the ground resistance of electric power transportation conductors and communication circuitry, this meter also measures the ground resistance of electric equipment and lightning arresters. - Page 17 Distribution of Electric Power The distribution of electric power on the ground is transmitted by wire shelf, every wire post has it’s own ground protection. Measurement mode as follows: Configuration of Telecommunications System To protect telephone lines from being interfered, the telecom maintenance department uses conduction wires to insulate the telephone lines.
- Page 18 Faraday Cage Protection System The principle of the Faraday Cage is that the conduction wire is connected with the ambient ground of one instrument, a group of equipment or one building. It can’t be interfered with externally. Application of Gas Stations Testing of ground resistance is necessary for gas stations to prevent static electricity.
