MVLV Electrical Reticulation: design, installation, Refurbishment & Commissioning of Electrical Systems and Equipment
Overview:
Today, the demand for technical skills and expertise in Medium Voltage/Low Voltage (MV/LV) electrical reticulation is increasing. It is the responsibility of companies, industries and municipalities to improve and educate their workforce to flow with the technological trend in MV/LV reticulation. Selections of appropriate MV/LV reticulation philosophy, equipment, cable sizing, fault level calculations, earthing design, protection schemes, etc. are crucial matters that determine any electrical reticulation's life span. Nowadays, several methods of MV/LV reticulation have been developed, for instance, philosophies like SWER, phase-to-phase systems, single-phase and dual-phase systems have evolved as the most cost-effective systems. However, MV/LV electrical reticulation methods are not always the same in a different environment; therefore, in-depth knowledge of reticulation methods is required by a designer to design a system that will provide maximum return on investment considering capital cost as well as operations and maintenance costs.
This intensive two-day workshop based on appropriate SANS and IEEE standards aims to expound reticulation practices by thoroughly explaining with detailed discussion and real-life practical examples of design, installation, refurbishment, and commissioning of MV/LV electrical reticulation.
