Inductive loads - the individual components Inductive loads - the individual components Inductive loads are usually specially designed for an application and with reference to the applicable norms. These standards detail the tests required but also the test setups and procedures. The inductances are specially adapted to the area of application so an optimal solution may be provided. Inductive load units are used when power supply systems or other test specimens, such as switches, contacts or frequency converters have to be loaded with a standardized effective and reactive power. Frequency converters that are loaded with an inductive load require substantially less energy when being tested, because compensation is effected by the DC intermediate-circuit capacitor. For this reason, only the losses are supplied for the testing, as a result of which an energy saving of approx. 70% - 80% can be achieved during such tests. Additional resistive loads are required to achieve the cos phi (power factor) values required for testing. This particularly applies to switch and contact testing. The application is used in development laboratories, proving grounds, test institutes, schools and universities.

Three-phase inductive loads Inductive load units Description The three-phase-inductive load consists of three iron-cored inductors, each with three tappings, and is used for testing static converters and switched-mode power supplies. The individual tappings are connected directly to the inductor. A REO DC closed loop current transformer is built in for each phase for measuring current. REOCHOKE 300 REOCHOKE 300 Technical data REOCHOKE 300 Voltage 3 x 4000 V Inductance values 3 x 1 mH with tappings at 0,75 mH, 0,5 mH and 0,25 mH Current 3 x 1500 A Tolerance of the inductor +/- 10 % IP Code IP 20 39
