A plant's electric load of VFD is +95%
Surge protection/lightning protection is required. These are 3 phase VFDs therefore +95% of the loads are three phase. The decision was made to make the system a 3 phase 3 wire based on this fact.
How can you utilize SPD/TVSS that work in this system voltage configuration?
The literature i have explored on SPD and TVSS from Square D point out that a solidly grounded system is a must to use this equipment. Is that true for all SPD/TVSS devices?
If there is no alternative but to make the system solidly grounded to accommodate for SPD/TVSS what are the pros and cons of making this change?
