1.       Applications

The basic purpose of a Neutral Ground Resistor is to limit the maximum electrical ground output to a safe value, protecting the generator and the other associated equipment without introducing a disproportionate download.

While the resistor may not be in constant use, it protects all equipment from getting burned if there was a failure. For this reason, we provide electrical grade stainless steel in all our resistors, ensuring that even when temperature increases, the ohmic value will remain the same.

Neutral grounding resistor are usually connected to the neutral power transformer or generator, allowing a quick take over of the failure to ground. The main benefit of the Neutral Ground Resistor is precisely its rapid and automatic ground loop isolation to a safe value, preventing any harm to the system or equipment.

2.       Mechanical characteristics

These banks of resistors are constructed under strict quality control ensuring isolation, voltage and temperature.

The construction of this resistor is based on galvanized steel by Angle-Dip or electrolyte plating, providing greater strength and allowing safe transportation and installation without risking misalignment.

As the standard indicates, the resistive elements are made of electrical grade stainless steel, mounted on a slab with high mechanical strength.

All the resistor components are auto-transported and assembled in store, being shipped as a complete unit without further need for later assembly.

Our voltage isolation system is based on ceramic insulators. For optimal protection, there are well above the standards.

According to the voltage system, the resistors are sometimes mounted on four insulating posts adding extra insulation and anchorage.

Finish

In order to prevent corrosion when installed outdoors or in places along the coast, the finish is galvanized either by dipping or electroplating.

It is also coated with a protective screen against rodents and birds that may harm the piece and affect its functioning.
