Matrix: Three Phase Systems

Email

Description

This pack (LK4961) is suitable for initial investigations into three-phase systems. The pack includes the parts needed to set up three-phase systems based on star and delta topologies with balanced and unbalanced loads. The pack allows power measurements to be understood and it includes a low voltage three-phase motor. A full-colour workbook with teachers’ notes is included. HP5834, 4 input Picoscope available as an accessory to this kit and also HP5561, a current clamp is available.
