Most attention was the production electricity and
it was not until the end the 1880s that the importance of
electrical measurement was appreciated.(Illus

in the 1880s. Precise electrical
measurement was the starting point the new art creating a
profitable load and controlling costs generating
electricity. The staff the galvanometer room (Building 1)
continually monitored the performance measuring equipment

At the user's end the system, the electric meter was
subject numerous complaints about its poor accuracy and
frequent breakdowns. This probably worked well enough the laboratory, but
proved ineffectual under normal operating conditions— it

the first three items the agenda were pressure meters,
