This study was developed to analyse whether type II protection was physically possible to achieve within neutral earthing resistor arrangements for 11 kV substations. Subsequent literature review was undergone to determine short fallings and knowledge gap confirmation to justify the studies relevance.

The missing information with respect to type II protection arrangements in neutral earthing resistors had not been considered within the scope outlaid for the study. Initiation of the project breakdown to determine the factors of design, arrangement, feasibility, potential learning, and dissection of results was undertaken, with full literature review to justify decisions and further previous works was considered.

The methodology of the study, review of principles and practices for academic improvement and critical assessment of methods to ensure accuracy was performed. Information from a real-world scenario was integrated to the project and simulation via software was undertaken to ensure the project met the standard of the engineering profession.

Dissection of results proved that implementation of the design in theoretical aspects would allow for an achievable system. The material analysis showed that implementation of the system was not possible utilising designed current industry accepted practice.

Conclusive analysis of the system, the methods, knowledge gap addressable topics and general learning was completed during the study that sufficiently addressed the topics objectives, aims and projected academic value adding. The studies goals of furthering the learning for neutral earthing were achieved, with the achievability of the design meeting significant hurdles which cannot be currently overcome without significant cost.
