galvanically การใช้

• If two electronic systems have a common ground, they are not galvanically isolated.
• Since 2005, the NFPA's NEC allows transformerless ( or non-galvanically ) inverters.
• However, since 2005, the NFPA's NEC allows transformerless, or non-galvanically isolated, inverters by removing the requirement that all solar electric systems be negative grounded and specifying new safety requirements.
