We have to understand the behaviour of each type of load when we do load calculations.
Understanding how to apply to different diversity in the different scenarios and the associated load graphs.
The effect of power factor correction in a system and to establish what power factor correction equipment is required. Teach a simple powerful method of fault calculation, where you can sit in a design meeting and provide answers in a jiffy. This will also assist in the size of a transformer for suitable motor
The theory of a transformer will be dealt with, where the principles of core losses and the different sizes of transformers and impedances will be addressed. Why there are different transformer impedances for different transformers and the application thereof? Standard vector grouping is used in the industries and discusses the typical types of cooling methods. Calculate the transformer voltage drop under different load scenarios. Explain the typical protection schemes for transformers and address the economic aspects. Give guidelines on the minimum specification for a transformer.
The different types of circuit breakers and insulation media i.e. SF6, vacuum, oil, and air will be discussed.
All the aspects of internal arc classification and IP ratings will be dealt with. Give guidelines on the minimum specification for switchgear.
Since protection is a specialist field and should be designed by a professional engineer. The aim of this course is to empower the design engineer with adequate knowledge to accommodate the protection systems with the assistance of the protection engineer.
Earthing can kill and damage property and equipment with substantial implications. The purpose of
this course is to understand earthing and the earthing requirements in terms of SANS and some supply
authorities. Earthing principles for typical transformer, miniature substation and large transformer
substation will be dealt with.
