By converting electrical energy into-
- Heat (resistors in toasters);
- Light (light bulbs);
- Acoustic energy (speakers);
- Storing energy (charging a battery).

Write down some Elements of Protection System.
Protection System Elements:
¤ Protective relays
¤ Circuit
breakers
¤ Current and
voltage transducers
¤ Communications
channels
¤ DC supply
system
¤ Control
cables
How Do Relays Detect Faults?
¤ When a
fault takes place, the current, voltage, frequency, and other electrical
variables behave in a peculiar way. For example:
o
Current suddenly increases
o
Voltage suddenly decreases
¤ Relays can
measure the currents and the voltages and detect that there is an overcurrent,
or an undervoltage, or a combination of both
¤ Many other
detection principles determine the design of protective relays
