Substation Power Engineering Fundamentals

Introduction

This Substation Power Engineering Fundamentals training course explores the types, characteristics, components and protection for electrical power substations. Power substations can be distinctly classified into two main categories one is outdoor, usually the air insulated substation (AIS) and the indoor gas insulated substation (GIS). Both substations have similar equipment and components, although the design of these equipment may differ. The main feature of the power substation is the type of transformers, they are visible in the transmission and distribution substations. The substation includes the overcurrent protection devices, the circuit breakers, the disconnector switches, instrument transformers including the lightning and surge protection devices. Progressively many new electrical installations are opting for the indoor gas insulated substation due to its safe, secure and reliable performance. In this digital age there is also a shift to futuristic digital substation complimented by state-of-the-art equipment.  

This training course will highlight: 

• The construction and characteristics of the air insulated substation and (AIS) the gas insulated substation (GIS)
• The operations of the various equipment in the power substations
• Fundamental and merits of gas insulated substation 
• Substation protection devices and equipment
• Futureproof digital substation
