用法筆記

EHT is primarily used in British and Commonwealth electrical engineering contexts. In American English the equivalent term is EHV (extra high voltage). The abbreviation appears most often in technical documentation, equipment labels, and safety signage — not in everyday conversation.

常見錯誤

❌The eht line is 110 V.
✅The eht line is 400 kV.
💡EHT refers to very high voltage (typically above 220 kV), not household-level voltage.
❌The engineer checked the eht on the battery.
✅The engineer checked the voltage on the battery.
💡EHT applies to power transmission infrastructure, not small-scale batteries.
