Energy

The majority of the collection consists of a set of rotating electrical machines, both direct current and alternating current. It includes experimental models of early machines used for converting mechanical energy into electrical energy and vice versa. Among domestic machines, the designs of František Křižík and Emila Kolbena (EAS, later ČKD) are particularly notable, but other domestic manufacturers (Bartelmus – Donát, Sousedík, Škoda, and others) are also represented in the collection. Later machines are primarily from the production programs of MEZ and ČKD Praha. The collection also includes traction motors for electric railways (Křižík) and electric vehicles (Kolben, Sousedík). Among foreign products, German and Austrian machines are more frequently represented. The collection also includes two high-frequency alternators of French provenance, which were used for transmission. This collection also encompasses controllers and motor starters.

Additionally, the collection contains equipment used for the distribution of electrical energy (disconnectors, switches, circuit breakers, isolators, complete distribution boards, contactors, fuses, small installation materials, etc.). In the field of high-voltage distribution, there is a complete control room for the 110/22kV substation. In the area of secondary electrical distribution, the production of ABB Elektro-Praga in Jablonec nad Nisou (originally Kramer & Löbel) is significantly represented.

The collection of chemical and thermoelectric power sources includes most types of galvanic cells used domestically, as well as several batteries of thermocouples heated by gas or liquid fuel burners.

The collection of electrostatic devices mostly consists of electrostatic sources—electric machines, demonstration aids for them, and not least, a collection of lightning rods. The most prominent object in this subgroup is a Van de Graaff generator obtained from the Nuclear Physics Institute of the Czech Academy of Sciences in Husinec – Řež.
