Yep, that´s my believe. We are focusing the fail hunt on the TCT (Capacitive transf) that bring the signal references from the generator line to the potential transformers that offer the signal for the syncronizer and other measurement instruments. Let´s see what we find! Thanks for the help, John. Regards, *Carlos* --Guri, Venezuela-- --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Seen that before. One section or one capacitor shorted will show a high apparent voltage and maybe low on another phase? Hence the high vars. By now you've fixed your problem.
