The following equipment is worthy of special mention:
A General Electric Educational Set consisting of a synchronous machine; a wound-rotor induction machine; a squirrel cage induction machine; and a double-current generator, each with a 15 k v a rating and wound for either 1, 2, 3 or 6 phase operation.
A Westinghouse synchronous motor-generator set, rated at 15 k v a and wound for 1, 2, 3 or 6 phases. One machine is arranged as a cradle dynamometer and equipped for phase shifting.
A General Electric sine-wave generator coupled to a synchronous motor. This machine generates a voltage wave which conforms accurately to standard wave form. It has a capacity of 5 k v a for three phases and has a ring gear mechanism for phase shifting.
A two-unit General Electric motor-generator set consisting of one 5 k v a generator capable of single-, three- or six-phase operation at 110/220 volts. This is coupled to a 5-kw, 250-volt d-c machine.
Three mercury-arc rectifiers complete with switchboards and auxiliaries.
Three General Electric Oscillographs complete with all auxiliary apparatus.
One Westinghouse four-element Oscillograph.
One Westinghouse Osiso.
One Sundt Neobeam Oscilloscope.
