Neutral Grounding Resistor

Having state-of-the-art production unit, we are able to manufacture, export and supply supreme quality array of Neutral Grounding Resistor. Connected between ground and neutral of generators and grounding transformers, this is used for resistance grounding of various industrial power system. The provided resistor is manufactured with the use of supreme quality raw materials and avant-garde techniques by our experts. Moreover, the offered Neutral Grounding Resistor can be purchased from us at economical rates.

Neutral Grounding Resistors are used for resistance grounding of industrial power system.They are grnerally connected between ground and neutral of transformers, generators and grounding transformers. Neutral Grounding resistors are used in order to limit maximum fault current to a value which will not damage the equipment in the power system, yet allow sufficient flow of fault currents with high resistance Neutral Grounding Resistors, earth short circuit current can be extremely reduced. As a result of this fact, protection divicesmay not sence the fault . Therefore, it is the most common application to limit single phase fault currents with low resistance Neutral Grounding Resistors to approximately rated current to transformer and / or generator.

Key Points:

  • Accurate dimension
  • Fine finish
  • Painted with synthetic enamel paint
  • Rust proof

Neutral Grounding Resistor

  • Then Neutral Grounding Resistor are painted with synthetic enamel paint of specified shade.
  • Other options are epoxy paint or aluminimum paint.
  • Pretreatment, which includes, degreasing rust/scale removing, phosphating as per applicable standards, is done followed by 2 coats of finishing paint of required shade. Ovendrying or stoving is done on request.

Advantages of using a neutral grounding resistor:

  • Reduced operation and
  • Maintenance expenses.
  • Fast isolation of the original fault.
  • Reduced transient over voltages.
  • Reduced physical damage on the
  • Equipment at fault.
  • Simplification of ground fault location.
  • Increased life and protection of
  • Transformers, generators and
  • Related equipment.
  • Reduced frequency of faults.
  • Improved service reliability.
  • Increased protection in the use of lightning arresters.
  • Increased safety for personnel
