Background: High-voltage transmission lines and power transformers need dependable protection systems which maintain their operational status to deliver continuous power distribution. Methods: The research used a quantitative cross-sectional survey design which gathered data from 250 power sector employees who worked as engineers and technicians and operators. The research employed descriptive statistics together with Pearson's correlation and multiple regression and ANOVA to study how people understood things and how they performed and used what they learned. The research team used Cronbach's alpha to evaluate instrument reliability for their study. Results: People view fast fault detection at 22 % and reduced downtime at 20 % and improved accuracy at 18 % as their main advantages. The main obstacles for system implementation consist of expensive startup expenses which affect 24 % of cases and complex technical requirements that impact 20 % and insufficient trained staff members who represent 18 percent. The evaluation of performance demonstrates that fault detection speed has improved by 20 % and reliability has improved by 19 %. The analysis shows that people who understand a system tend to adopt it more (r = 0.45) and those who receive training develop better implementation skills (r = 0.41) but the cost factor creates a negative impact on adoption rates (r = −0.38). Conclusion: Digital protection systems provide power systems with better performance and enhanced reliability through their operation. Strategic investment along with capacity building and supportive policies need to exist for power systems to achieve successful implementation and modernization.
