#123005 - True, however Responding to: ???'s previous message |
Many professional power meters get their supply from mains and aren't isolated from mains!
True, however, they are (I hope) developed in environments with isolation transformers for the mains supply, insulated floors, and several other safety precautions. I doubt that will be the case for a student project. Were I to develop a 'home use energy meter' would I use transformers - heck no. Would I agree to develop it if the lab did not have each and every safety feature - heck no. Erik |
