Hello Everyone
Today I came across something new, or rather new to me. The plant is fairly old and not well maintained so drawings are really not available. Can anyone help.
The compressor is/are a Copeland 6RP2-3500 TSE and the nameplate has them at 565volt/60 Hz or 500volt/50 Hz.
The plant is 415v 3phase and the wiring to start with would have one believe it was a star delta starter. However at a closer look it there is only one 3 core cable going to the compressor and there is transformer which seems to be connected to a contactor but only on two phases. Anybody have any ideas?
Many Thanks
