Does an integrated UPS bypass circuit require a transformer
Adding a bypass isolation transformer allows an electrical contractor to earth the UPS output neutral, eliminating this problem. This galvanic isolation protects against electric shock, suppresses electrical noise to sensitive devices. Changing a mains system can be needed in several application: for instance, most of the IT load needs TN-S systems but it's possible that the local grounding system is TN-C or IT, or, in other cases, the load is placed in an area where the neutral must be isolated (it is typical in medical. When generators are installed, it is common to use four pole changeover switchgear or contactors when transferring from mains to generator, resulting in the traditional neu...
