In 230/240 VAC the neutral side of the transformer output is earthed at the transformer end. So breakdowns in the transformer go direct to earth at the distribution transformer itself. At the customer end you will find a small voltage at the neutral terminal due to the current running down the resistance of the conductor back to the transformer. As this is not a balanced supply, outlets have specific connections to each pole of the mains and earth. The earth connection is made locally, usually bonded to the incoming water main. 73 Steve -- Steve Rooke - ZL3TUV & G8KVD Omnium finis imminet _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
