Training Earthing System in Substations

Training Earthing System in Substations


Substation earthing system is essential not only to provide the protection of people working in the vicinity of earthed facilities and equipment against danger of electric shock but to maintain proper function of electrical system. Reliability and security are to be taken in considerations as well as adherence to statutory obligations and Indonesian standards on electrical safety. Earthing system design, thus, must be easily maintained and future expansion must be taken into account while designing the dimensions of earth mat. This course covers all details of an Earithing System in Substations including design, installation, and maintenance of the system.
