Lab-Volt / LabVolt EMS 8321 Inductive Load / Variable Inductance / Three Phase Load / Circuit Element

The Inductive Load Module, Model 8321, is equipped with 9 iron-core power inductors, which have a nominal Q of 10. Each inductor is identified by a schematic symbol, the inductance value, the inductive reactance, as well as the current that will flow through it when connected to a nominal voltage power source. Each inductor is within 5% tolerance of the stated inductance value.

Lab-Volt EMS..

The Lab-Volt 0.2 kW Electromechanical Training System (EMS) features four electrical load modules: the Resistive Load, Model 8311, Inductive Load, Model 8321, Capacitive Load, Model 8331, and the Inductive and Capacitive Loads, Model 833 (all available at TSS) 3. Each model comes as half-size EMS module. The loads are identified on the module front panel by schematic symbols and enabled using toggle switches. Connections are made through 4 mm safety banana jacks.

These models provide impedance levels that are adjustable for load equality, allowing students to measure the effects of indentical resistive and reactive loads on voltage and current in a circuit, as well as observe, using a wattmeter or a varmeter, the differences that each type of load has on an ac signal source. Furthermore, because complex loads are possible through the interconnection of these models, power factor correction and resonance phenomena are easily demonstrated in laboratory exercises.
