The Sunbury generating plant consisted of an Armington & Sims engine driving two small Edison dynamos having a total capacity of about four hundred lamps of 16 c.p. The indicating instruments were of the crudest construction, consisting of two voltmeters connected by "pressure wires" to the centre of electrical distribution.

In the case of a turbo-alternator the steadiness obtainable in the electrical load may determine the frequency of readings taken, both electrical and otherwise. On a perfectly steady water-tank load, for example, it may be sufficiently adequate to read all wattmeters, voltmeters, and ammeters from standard instruments at from one- to two-minute intervals.

The technicians checked their recording voltmeters and ammeters and reported that, sure enough, some ten kilowatts of power at a little less than one hundred fifteen volts D.C. was coming from the Black Suitcase. Sorensen and Thorn sat in the tent which had been erected to ward off the sun's rays. They watched the lights shine.

Douglass, you move that magnetostat apparatus out of the way, and leave just the 'can-opener' of ours the projector. I'm pretty sure that's what does the deed. Devin, see if you can hunt up some electrostatic voltmeters with a range in the neighborhood of I think it'll be about eighty thousand." Rapidly, Douglass was dismounting the apparatus, as Devin started for the stock room.
