An induction motor works by using electromagnetic induction to generate a rotating magnetic field.

• An induction motor consists of a stator and a rotor.

• The stator has a set of windings that are connected to an AC power source.

• When the AC power is applied, it creates a rotating magnetic field in the stator.

• The rotating magnetic field induces currents in the rotor windings, which in turn creates a magnetic field in the rot...read more

Differential relays are typically located at the ends of a protected zone.

• Differential relays are used to detect faults within a protected zone

• They compare the current entering and leaving the zone

• If there is a difference, it indicates a fault

• The relay is typically located at the end of the zone closest to the source

• This allows for the quickest detection and isolation of faults
