Sep 21, 2012 · The equipment ground can be made up of metal enclosures and metal raceway, but generally is a separate, conductor with green insulation (or green phase tape marking in larger conductor sizes). The equipment grounding conductor is non-current carrying, and therefore is isolated from the neutral except at the aforementioned bonding/grounding point. A network transformer may be submersible or vault. It usually, but not always, has a provision for attaching a network protector (from IEEE C57.12.80-1978). Dry transformers are also used for spot network applications. Network unit: A network unit consists of a primary disconnect and grounding switch, a network transformer, and a network protector. Figure 1 shows three single-phase transformers with one-to-one ratio that are connected as a grounding bank. The windings of the zig-zag transformer are connected such that under normal system operation, the magnetic flux in the three windings will cancel each other, and a negligible current (high impedance) will flow in the neutral (Ig ≈ 0).Chinese symbol for pubg name
