We have an old GE street lighting transformer (constant current regulator) that has been in the shop about once per year for various failures. It is presently at a repair facility with orders to upgrade the control scheme. The technical personnel there is familiar with these regulators, but has never seen the control scheme on our unit and can't identify all the components. It was installed in 1956. I've tried all the GE channels I know and submitted the following information with no success. I'm asking if anyone out there knows of a guy in retirement somewhere that may know where GE's drawings are for these units.
