Transformer and generator neutral grounding

Grounding through resistors of neutrals of transformers and generators is widespread in medium and high voltage industrial systems due to its obvious advantages:

 

  • Reduction of earth fault current to safe values until safety devices enter operation to prevent damage to equipment.
  • Increased safety by reducing transient overvoltage.
  • Reduction in the number of spurious trips.
  • Ease of troubleshooting.
  • Simplicity of operation and maintenance.

BASIC FEATURES

  1. Ohmic value.
  2. Through default.
  3. Timing of default.
  4. Level of insulation.
  5. Degree of protection of the envelope.
  6. Elements to be incorporated in the resistor:Current and/or voltage transformers, switchgear, temperature control elements, heating resistors, etc.
