Measurement ground resistance. What are the soil conditions? Normal and loose soil steel pipe 17 mm sufficient. When the appropriate value reached, driving interrup- ted and the last extension tube is withdrawn (and can therefore be reused). heavier soil/at greater depth, a power hammer should used. If the stone does not shatter after about 10 seconds, you must start over. mm² line should folded double before the tip attached. Make sure that the line maintains the same speed down into the soil the rod. 4. 1. Practical advice: 1. Resistivity different soil conditions. 2.11:3 11 Structure and operation the system Elpress systems consist the following parts: • hardened steel tip • leading rod • extension rod • driving sleeve/impact sleeve • earth line (not supplied Elpress) This feature simple • the earth line inserted into the hardened steel tip and clamped the leading rod. - the rod continues and the line stops; the line has come loose and can pulled up or the tip has folded. Start the driving locking the line into the hardened tip with the leading rod. Based on that and the maximum earthing resistan- ce can estimated how much line is needed. does not, there are the following possibilities: - more rods than line required; the rod may have been bent and then runs parallel the surface the soil and the line does not follow the pipe through the ground. loose soil, a sledgehammer and impact stud suffi- cient. Arrange parallel earth connection necessary. In the event interrupted driving, start again distance least 1. Driving starts. • the extension rods are fitted with a guide pin, which during work pushed into the preceding rod.5 times the line length already driven down. 5. Hard and rocky soil- steel rod mm (type HD) should used. NOTE: Do not rotate the driving sleeve during the work. • earthing resistance can measured continuously. Plan the earth connection. Splicing and bran- ching the earth line contact crimped by means Elpress through connectors or branching sleeves and tools. The earth line locked the hardened steel tip with the leading rod. . Preferably measure the earthing resi- stance continuously while driving down the earth line. parallel earth connection possible? 2. 3. 3. - both stop; stone rock has been found.
