Each unit consists of a steam turbine coupled di- the same level as the condenser, and are driven by worm-gearing from the turbine shaft, making the whole plantself-contained. The normal voltage is 500 volts, and the machines are(fitted with the Parsons electrical solenoid i governor, which maintains a constantvoltage on the supply mains. Mechani-cal safety governors are also fitted for thepurpose of coming into action when tin-speed rises to a certain height and entirelycut off the steam. The plants are designedfor a steam pressure, at the stop valve, of135 lbs., and are complete with oil coolers,oil trays, etc. We now come to the most importantpart of the new work which the HalifaxCorporation has been carrying out, re-ferred to a
