Description

The equipment listed in this brochure is designed especially for educational purposes. The motors, generators, load units and power supply units are interchangeable so that in addition to the listed experiments it is also possible to demonstrate installation wiring requirements, meter connections, motor symptoms during overload and many other important conditions necessary in different syllabis. A brief synopsis of experimental coverage is given below.
