Neutral Grounding Resistor By Stesa Littelema Electricals Pvt. Ltd.

These Neutral Grounding Resistors are generally employed in the LV and MV distribution networks to protect power transformers and generators from damaging currents in the event of earth fault.
To limit the damages to the electrical equipment, such as switchgear, transformers, cable and rotating machine and to prevent the extension of the fault with benefit also for the safety of the personnel
to protect the conductors and the system equipments from overheating and mechanical stresses
In many low and medium voltage systems, the system neutral may not be available. This is specifically true on Delta and ungrounded Wye Connected systems. To be able to ground these systems, grounding transformer (Zigzag or Wye-Delta type) can be used to create a neutral, which in turn can be connected to ground either directly, or more commonly, through a Neutral Grounding Resistor. These combinations are known as artificial neutrals and in each of them is possible to install a Neutral Grounding resistor.
