SILABUS TRAINING POWER TRANSFORMERS

Deskripsi Training  Power Transformers

Electrical Transformer discusses how units are used to reduce voltage for various day-to-day electrical applications. More than 50 million electrical distribution transformers are located on utility poles and cement pads across the United States and Canada.

Electrical Transformers serve the crucial function of transforming voltage potential to a higher or lower values to meet the appliances and machinery voltage level requirements.

Improper use, maintenance and neglect can cause heavy losses to businesses as well as to the environment. This electrical transformer training course introduces basic safe operational and field diagnostics of transformers with the focus on safe operation, testing and maintenance of the distribution transformers normally installed in substations and on poles.

Students will learn Electrical Transformer Basics – safe and proper maintenance and testing procedures on power transformers. The course covers transformers used in commercial and industrial power distribution systems, including oil and dry-type units. Larger power transformers used in utility applications are also covered.

Menimbang cukup kompleknya materi pelatihan Power Transoformers ini bagi peserta, dibutuhkan training provider yang berpengalaman di bidangnya agar tidak membuat peserta tidak menjadi cepat bosan dan jenuh dalam mendalami bidang teknik ini.
