A current transformer is a type of instrument transformer that is used to step down high currents to a lower, more manageable level for measurement and protection purposes.

• Used to measure high currents in power systems

• Consists of a primary winding and a secondary winding

• Output current is proportional to the input current

• Commonly used in conjunction with ammeters and protective relays

• Example: A 1000:5 current transforme...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire (primary and secondary) wrapped around a core

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy to the secondary circuit

• Used to step up or step down voltage levels i

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by excess current.

• A circuit breaker automatically interrupts the flow of electricity when it detects a fault or overload in the circuit.

• It is designed to prevent overheating and potential fires in electrical systems.

• Circuit breakers come in different types such as thermal, magnetic, and hybrid.

• Examples of circuit brea...read more
