1930 Eicr

Kelly Marie Angel

Interesting stuff I didn't even know they did EICRs back in the day  guess it proves nothings new. Not sure about AC being more dangerouse than DC  letsface it anything more than 110 volts will be moderately unpleasant to down right painful

  • Back in the good old days of DC mains, distribution was often at 11kv 3 phase AC with a stepdown transformer and a rotary converter to produce DC nearer the load. Mercury arc rectifiers were sometimes used, but rotary converters gave a smoother output and the voltage could be adjusted by manipulating the field current in the rotary.

    The earlier rotary converter substations were manned, but later they were automated.
