Field Loss Relay

A protective device in electrical engineering that detects the loss of magnetic field in a generator and prevents generator damage by disconnecting it from the load or system.

Shunt Field

A winding in electrical machinery, placed in parallel with the armature, used to create a constant magnetic field.

Armature

A component of electric machines, typically rotating, that acts in conjunction with a magnetic field to produce electrical energy (in a generator) or mechanical energy (in a motor).
