    I remember the first time opening a door on a big starter and thinking WTF . The dash pots at the bottom and the little jars of oil were laying on their sides with an oil stains. The wire was al. and covered in tar and canvas, more then likely asbestos wrap. Open transition and sounded like a shot gun going off when it would pull in. Made me jump every time. That old Carrier would whine spooling up , chirp the gears and dim the lights when it would transition.
    We just got rid of our last wye-delta starter over the winter that was on a York and but in a chiller with scrolls and we still have a 19C with a wye-delta starter on it. It gets run once a week.

    Used to be fun commissioning the old Trane Air Cooled Centravacs, get the customer and consultant inside the cabin while I stood in the door when I fired it up and it started to shake rattle and roll, the look of panic on their faces :-) trying to get out of the cabin

    Not so much fun nowadays , contractors, customers and consultants looking for paint scratches and faults so they can delay payments or get extended warranty or discounts, plus generally the gear was more robust and you could get it working, nowadays you can get screwed if you don't know the password or the fault is software. We used to lug around a big DC injector box to calibrate the oil filled dashpots, taking off the arc chutes and cleaning the carbon off the contacts, watching the closed transition springs bounce as the switched from star to delta, that was before they went to insulated resistors. Now it is just a gradual winding up on a vsd and the high pitched sound of the frequencies and flashing led's

    Yes, nice, as long as you did your maintenance properly they were reliable and didn't break, when we used to get calls from customers in those days our first reaction was 'what have they (the customer ) done to break it, whereas now it more a case of what board, software/hardware defect have we got now and how much damage has it caused.

    Yes, I know that feeling but we have to trade off the efficiency we get now and try to get customers to stock parts with the money they save in electrical consumption , lol

    You get gained efficiency on a VSD but not on a solid state starter.
