Final answer:
Three common types of monitoring and control systems used in transmission and distribution are circuit breakers and fuses for preventing thermal hazards, GFCIs to prevent electrical shocks, and the three-wire system for safeguarding against thermal and shock hazards.
Step-by-step explanation:
Monitoring and control systems are essential in the management of transmission and distribution networks in the electrical industry. Here are three types of systems often used:
- Circuit breakers and fuses - These devices are designed to interrupt excessive currents to prevent thermal hazards. Circuit breakers can be reset after tripping, whereas fuses must be replaced.
- Ground Fault Circuit Interrupter (GFCI) - Also known as a ground fault interrupter (GFI), this device prevents electrical shock by detecting loss of current to unintentional paths. If an imbalance is detected, it quickly cuts off the power supply to prevent injury.
- Three-wire system - This system includes live/hot, neutral, and ground wires. It guards against thermal and shock hazards by grounding the neutral wire and the case of the appliance. This ensures safe operation and efficient transmission along power lines.
Transformers, while not a control system, play a vital role in electrical safety and are discussed in Electrical Safety: Systems and Devices. They are used to adjust the voltage from the electrical power plant for safe and efficient transmission. Moreover, these systems often utilize induction as part of their functionality to ensure safety and regulatory compliance.
