Transformer Primary & Secondary Protection based on National Electrical Code

Part of our job as an engineer is to check the design of other designers, engineers and of electrical product manufacturers. We call this QA/QC or Quality Assurance and Quality Control. Most companies have this system in place. It is a process to make sure that deliverables are thoroughly checked before they go for construction. […]

Power Systems Protection & Control – The Anti-Pumping Relay Application

Background – The Anti-Pumping Relay Function In power systems protection, the control circuits of circuit breakers are designed in such a way to prevent the circuit breaker from closing and opening multiple times successively as it will damage the breaker closing mechanism. Imagine this scenario, the operator turned the control switch in order to […]
