Category: Utility Scale Generation
Commercial and utility scale solar installations are often required by the utility to provide grounding transformer as part of the overall installation's requirement to provide "effective grounding" per Article 100 of the N.E.C. Grounding transformers are not specified or sized like typical distribution transformers. Some of the sizing values may be not known until the solar project is well underway. If a specifier is not aware of the overall design and specification requirements for grounding transformers, the product may not be ordered properly or in time to meet utility requirements to energize the solar installation.
The presentation is geared to discuss the proper utilization and specifications need by specification engineers, EPC's and electrical contractors to select the proper grounding transformer. Grounding transformers are unique to each installation and are made to order. Any errors or missing data can result in delays of weeks or months in procuring the product.
