Motor Protection Lab Experiment Using Sel-710, Ozro Corulli
Electrical Engineering
Advancements in microprocessor based relay technology for power protection applications provide quicker response times and new methods of mitigation. This project develops a lab experiment for Cal Poly class EE444 - Power Systems Laboratory based on the Schweitzer SEL-710 motor protection relay. Learning objectives for this lab include relay setup, programming, and protection schemes for the following conditions: undervoltage, loss of phase, fault, locked rotor, and thermal overload. Today, utility companies across the globe use SEL relays for primary system protection, putting engineers familiar with their operation in high demand.

Theses and Dissertations - UTB/UTPA
Engineers are tasked and responsible for studying and designing environmentally safer forms of electrical generation including wind and solar sources. A national effort to reduce dependency on foreign oil due to economic and environmental impacts is underway and race to full scale implementation of alternate energy sources is eminent. The question looms: Is renewable energy generation for residences feasible from an engineering and economic perspective? Although wind and solar generators are gaining ground on conventional generation methods in different sectors, lack of information with regards to design, implementation, and payback still remain a major roadblock. The objective of this case …

National Infrastructure Protection Priorities For Nuclear Electromagnetic Pulse (Emp) And Solar Storm Geomagnetic Disturbance Catastrophes, George H. Baker Iii

The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP and geomagnetic disturbances (GMD) caused by severe solar storms. Similar to protecting critical infrastructure against any hazard, it will be important to take a risk-based priority approach for these two electromagnetic threats, recognizing that it will be fiscally impracticable to protect everything. In this regard, EMP and GMD are particularly challenging in that they interfere with electrical and electronic data, control, transmission, and communication systems organic to nearly all critical infrastructures, simultaneously, …
