To choose the kind of earth electrode to be used, must be considered first local conditions, soil properties and resistance grounding is allowed. The surface of the earth electrode should relate well with the surrounding soil. Stone and gravel directly on the earth electrode, will increase earthing prisoners. Electrode rod, inserted perpendicularly into the ground and adjustable length with the necessary grounding prisoners.
Prisoners earthing is largely dependent on the length and less dependent on the size of the cross section. If multiple electrodes required to obtain a low earthing prisoners, then The minimum distance between the electrodes should be twice as long. If It The electrodes do not work effectively on the entire length, then The minimum distance between the electrodes, the length should be twice as effective.
Earth conductor must be fitted with a removable connection to earthing prisoners testing purposes, in a place easily achieved and where possible, take advantage of the connection because installation arrangement must exist.
Earth conductor connection earth electrode, must be mechanically strong and ensure the relationship electricity well, for example by using welding, clamps or bolts keys are not easily separated. Clamp on the pipe electrode, must using bolts with a minimum diameter of 10 mm.
Grouping and use of the instruments of labor.
- Working tools can be grouped into 4 (four), namely
- Tools, Measurement and Testing, Safety Equipment, and Tools.
- To facilitate the grouping / sorting tools work on a project, the following are given names and images of equipment for a variety of jobs. A large project requires special tools that are not working at the site. Therefore procurement should be scheduled in a timely manner.
Electrical Tekniksi installing electrical installations in buildings, required skills in various fields of work in the building. This includes techniques marking, cutting, chiseling and sawing.
