EENG 452 — PROTECTIVE RELAYS and PROTECTIVE RELAYS LAB
Learning Objectives & Matches
2. Understand the reliability of protective relays
Relay messages about emergencies, accidents, locations of crew and personnel, and fire hazard conditions.
Open and close switches to isolate defective relays, performing adjustments or repairs.
Relay complaint and emergency-request information to appropriate agency dispatchers.
Respond to emergencies, such as transformer or transmission line failures, and route current around affected areas.
Assess security needs across locations to ensure proper deployment of loss prevention resources, such as staff and technology.
Direct the purchase, modification, installation, testing, maintenance, and operation of fire prevention and protection systems.
Determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment.
Relay information and messages to and from emergency sites, to law enforcement agencies, and to all other individuals or groups requiring notification.
Relay or route written or verbal messages.
Verify correct use and maintenance of physical security systems, such as closed-circuit television, merchandise tags, and burglar alarms.
3. Understand issues of current transformers associated with protective relays
Respond to emergencies, such as transformer or transmission line failures, and route current around affected areas.
Relay complaint and emergency-request information to appropriate agency dispatchers.
Connect wires to circuit breakers, transformers, or other components.
Relay messages about emergencies, accidents, locations of crew and personnel, and fire hazard conditions.
Identify defective sectionalizing devices, circuit breakers, fuses, voltage regulators, transformers, switches, relays, or wiring, using wiring diagrams and electrical-testing instruments.
Determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment.
Install, maintain, and repair electrical distribution and transmission systems, including conduits, cables, wires, and related equipment, such as transformers, circuit breakers, and switches.
Identify and communicate power system emergencies.
Inspect electrical connections, wiring, relays, charging resistance boxes, and storage batteries, following wiring diagrams.
Open and close switches to isolate defective relays, performing adjustments or repairs.
4. Understand non-pilot protection of transmission lines
Travel in trucks, helicopters, and airplanes to inspect lines for freedom from obstruction and adequacy of insulation.
Respond to emergencies, such as transformer or transmission line failures, and route current around affected areas.
Prevent ships under navigational control from engaging in unsafe operations.
String transmission lines or cables through ducts or conduits, under the ground, through equipment, or to towers.
Follow safety procedures to ensure the protection of passengers, cargo, and vessels.
Direct security activities at derailments, fires, floods, or strikes involving railroad property.
Relay departure, arrival, delay, aircraft and airfield status, and other pertinent information to upline controlling agencies.
Signal passing vessels, using whistles, flashing lights, flags, or radios.
Coordinate communications between air traffic control and maintenance personnel.
Relay messages about emergencies, accidents, locations of crew and personnel, and fire hazard conditions.
