Description
The EDU-LABS EM86386 Three Phase Power System Trainer familiarizes students with three-phase power systems. The system first introduces the student to the fundamentals of three-phase power systems, such as the wye (star) and delta configurations, phase and line voltages, phase and line currents, phase balance, etc. Students then examine how to measure power in three-phase circuits using the two-wattmeter method, as well as how to determine the power factor. Finally, students explore the phase sequence and learn to determine the phase sequence of a three-phase power system.
The system consists of a series of modular slot-in panels modules housed in a compact epoxy coated casing. Each modules represents one or more electrical / electronic components or on block diagram of a complex circuits. All functional parts of the components are mounted inside the modules with circuit symbols/mimic diagrams screen printed on the front PCB panel and terminated at 4mm safety sockets for student experimental practice.
All modular slot-in panels modules are inter connecting together by using 19mm short circuit shunt and / or 4mm stackable safety test leads sets to form the desired control circuits.
EXPERIMENT COVERAGE:
- Analyze three-phase circuits and learn to solve them.
- Discover the difference between line and phase voltages and currents.
- Calculate the active power dissipated in each phase of a three-phase circuit and the total active power dissipated in a circuit.
- Learn about phase sequence and wye and delta circuit configuration.
- Calculate the active, reactive, and apparent power in balanced, wye- or delta-connected, three-phase circuits.
- Analyze the phase sequence of a three-phase circuit using an oscilloscope.
