A Glass Relay is a type of electrical relay that uses a glass tube to enclose the contacts and arc extinguishing medium.
_Working Principle:_
1. The glass tube is filled with an inert gas, such as nitrogen or argon.
2. When the relay is energized, the contacts inside the tube close or open.
3. If an arc forms, the gas inside the tube extinguishes it.
_Classification:_
1. _By Application:_
- Control Relays
- Protection Relays
- Interface Relays
2. _By Contact Configuration:_
- Single-Pole Single-Throw (SPST)
- Single-Pole Double-Throw (SPDT)
- Double-Pole Double-Throw (DPDT)
_Application:_
1. _Industrial Control Systems:_ Used in manufacturing, processing, and automation.
2. _Power Systems:_ Used in electrical substations, transmission, and distribution.
3. _Communication Systems:_
