What are generator neutral earthing resistances
Click For Summary
SUMMARY
Generator neutral earthing resistances are devices that limit fault current and are generally not required for small generators, such as a 50 KW 3-phase 120/208V unit, unless specific applications demand them. The necessity of these resistances depends on the operational context, particularly when running multiple generators in parallel. In such cases, additional safety measures like a stator winding fault relay may be advisable to enhance protection and reliability.
