Earthing/Grounding Transformer Product Details：
General:
In some situation, the system neutral may not be available. To be able to ground these systems, earthing /grounding transformers 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 (NGR). These combinations are known as artificial neutrals.
Standards:
Ø IEC-76 .1-1993 Power Transformers: general
Ø IEC-60076 Power Transformers
Ø JB/T3837-1996 Approaches for Editing Type of Transformer
