The Basics of Bonding and Grounding Transformers | EC&M
Note in the photo how the 3/0 AWG bare copper grounding electrode conductor originates from the neutral point XO and pierces through the mesh in the bottom of the transformer enclosure. Because the grounding electrode conductor is not solidly bonded to the transformer enclosure, this is no compliant system bonding jumper for this separately

Wiring Diagrams and Grounding: Electrical Online
Wiring diagrams on our site usually don’t include the ground connections but this does not diminish the importance of grounding. I do this to avoid clutter on the wiring diagrams, and to focus on how to make the circuit work the way it should.
06 System Grounding - Schneider Electric
PDF fileThe system grounding arrangement is determined by the grounding of the power source. For commercial and industrial systems, the types of power sources generally fall into four broad categories: A Utility Service – The system grounding is usually determined by the secondary winding configuration of the upstream utility substation transformer.
Easy understanding of 3-phase transformer connections
The single-phase load can be fed by grounding a center tap on one of the legs of the delta secondary, Wye–Wye Transformer Connections Diagram The wye–delta transformer shown in Figure 9 is sometimes used to provide a neutral on a three-wire system but also can serve load from its secondary.

Transformer Grounding | The Electricity Forum
Grounding of Neutral Grounding Devices (Impedance Grounding). Where neutral grounding devices are used, warning signs indicating that the system is impedance grounded and the maximum voltage at which the neutral may be operating relative to ground shall be placed at the transformer.
Why is neutral wire connected to ground at the transformer?
Why doesn't the neutral wire go back to the power generation plants. The diagram you provided hints at this. There is no connection between the three-phase, high voltage primary and the low-voltage secondary. The supply is feeding a three-phase transformer without a neutral on the primary side.
3 phase transformer grounding & bonding - ECN Electrical
I am installing a 45kva 3 phase delta-wye 480/208/120 transformer in a vehicle repair shop. The transformer primary will be connected to a breaker in the 480/277 building service panel. The transformer secondary will feed a 100 amp 208/120 panel for power and lighting. I want to be certa..
ZigZag Transformer Connection Overview - EEP
The zigzag transformer contains six coils on three cores. If we need a neutral for grounding or for supplying single-phase line to neutral loads when working with a 3-wire, vector diagram of znyn11. Reply. Woodlice. Aug 02, 2018. Exactly what i needed to know — Thanks. Reply.
