GIS and AIS are two types of switchgear used in power systems.
GIS stands for Gas Insulated Switchgear and uses SF6 gas as insulation.
AIS stands for Air Insulated Switchgear and uses air as insulation.
GIS is more compact and requires less maintenance than AIS.
AIS is less expensive than GIS.
GIS is used in high voltage applications while AIS is used in low to medium voltage applications.

A relay is an electrically operated switch that uses an electromagnet to mechanically operate a switch.
Relays are used to control high power circuits with low power signals
They can be used for various applications such as controlling motors, lights, and heating elements
Types of relays include electromagnetic relays, solid-state relays, thermal relays, and reed relays
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Circuit breakers automatically detect faults in the electrical system and interrupt the flow of electricity to prevent damage.
They come in different types such as thermal-magnetic, magnetic, and hydraulic-magnetic circuit breakers.
Common examples include miniature circuit breakers (MCB), m...
A resistor is an electrical component that resists the flow of electric current. There are various types of resistors based on their construction and materials used.
Resistors are used to limit the flow of current in a circuit.
Types of resistors include carbon film, metal film, wirewound, and variable resistors.
Resistors are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.
A resistor is an electrical component that resists the flow of electrical current, causing a drop in voltage.
Resistors are used to control the amount of current flowing in a circuit.
They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.
Resistors can be fixed or variable, with variable resistors allowing for adjustable resistance.
Examples of resistors include carbon film resistors,
A diode is a semiconductor device that allows current to flow in one direction only.
Diodes are made of semiconductor materials such as silicon or germanium.
They have two terminals - an anode (positive) and a cathode (negative).
When a voltage is applied across the diode in the forward direction, it allows current to flow.
In the reverse direction, the diode blocks the current flow.
Diodes are commonly used in rectifiers, ...
A diode is a semiconductor device that allows current to flow in one direction only. Types include PN junction diode, Zener diode, Schottky diode, and LED.
