This pack 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, current clamp is also available.
