These days, you will find several companies that develop Grounding Transformer and systems that are in different designs. The most common applications for these types of transformers are a three phase zigzag Grounding Transformer for mines, power systems and utilities. These transformers are also used for high resistance grounding which is becoming increasingly important on various companies worldwide.

Purpose

The Grounding Transformer is typically used to provide relatively low impedance path for the ground that helps to keep the system neutral or to remain at near ground potential. The transformer also helps to limit the magnitude of the transient on voltages in case re-striking of the ground will occur. It also provides a source of ground fault current in the event of line to ground faults. Furthermore, neutral Grounding Transformer and systems can allow the connection of phase to neutral loads if needed. Neutral Grounding and Furnace Transformer such as these can either come as single or three phases in order to help protect equipment from any faults. It is important to look for a supplier that can provide ...
... grounding units that are built with UL recognized insulation system that helps to meet the requirements of various applications.

Applications

The various applications of the grounding as well as the Furnace Transformer include the following:

• a 3-phase zigzag grounding both limited duty as well as continuous duty

• a 3-phase applications that comes with electric utility power systems, commercial power systems, mine power systems, as well as high resistance grounding

• a single phase Grounding Transformer as well as grounding systems used for electric utilities and other purposes

It is important to look for a supplier that has several validated designs of Grounding Transformer. This means that they can help t o lessen the time and risk for customers. Some of the transformer manufacturers these days are often too slow to respond. A good supplier is one that provides a two day turn around on several quotations and usually delivers new design as well as approval drawings in only a few days.

Earthing

The Grounding Transformer is also known as the Earthing transformer. Each of the three limbs of these transformers is often divided into two sections. The two halves of each of the limb are often equivalent to the number of turns and they are usually wounded on various opposite directions. While the neutral is being grounded, during which a phase to ground short fault, the third of current will return to the fault current and then the remainder should go through those two of the three phases whenever it is being used to derive a grounding point that comes from a delta source.

The Neutral Grounding Transformer is also similar to fuses in the sense that they do nothing until such time that something in the system goes wrong. Just like the fuses, they help to protect the personnel as well as the equipment from further damage. The damage often comes from two factors. First is how long the fault lasts and another is how large the fault current is.
