This Watthour Meter was originally used to measure direct current energy at the Canmore Coal Mine, prior to shutting down in 1979.  It was added to the EPHF Museum collection in October 2014.    Thompson Watthour Meter General Electric ...

Westinghouse Phase Meter, circa 1930, displays degree displacement between AC current & voltage inputs.

General Electric Alternating current ammeter circa 1914, with a mirrored scale for reading accuracy, manufactured after 1914. Prior to 1914 the Thomson name was on most GE measuring equipment nameplates. 

Electrical power in North America is generated at 60 cycles per per second A Micromax recorder similar to this one built by Leads & Northrup was used in both Rossdale and Clover Bar generating Stations this particular instrument is from the old Celanese ...

On display at the museum is an oil circuit breaker (OCB) from 1937. The function of a circuit breaker in a substation is fundamentally the same as the circuit breakers in your home in your electrical panel. If an overload (short circuit e.g.) occurs on ...

This is a small turbine used to drive a pump or fan in industry Steam turbines are HEAT engines   They convert the heat energy from steam into mechanical energy that rotates the shaft.   Nozzle: First converts heat into kinetic energy  by ...

Come out to the Museum and try out the Game These are photos of the screen as the display is played  

This little model illustrates how moving a magnet past a coil of wire produces electricity. This fundamental technology of converting mechanical energy into electrical energy, first demonstrated by Michael Faraday in 1832, underpins virtually every type ...

Flyball Governors are used to maintain Engines or Turbines at a "constant" speed.The faster the shaft is turned the farther the balls will swing out , due to centrifugal force.This motion is transmitted through linkage to close a valve supplying Steam ...
