Power Analyser CASSY

The Power Analyser CASSY is a combination of an isolated and differential oscilloscope, multimeter, wattmeter, energy analyser and recorder. It is designed for demonstration and laboratory experiments.

 The Power Analyser CASSY differs from its previous model in that it has an additional LAN connection.

The Power Analyser CASSY is suited to the following areas of application:

Power grids

• Voltage and frequency stability
• Load behaviour of networks
• Effect of harmonics

Electrical machines

• Inrush current from transformers and machines
• Transformation ratio of transformers
• Efficiency of machines

Power electronics

• Rectifier
• DC/DC converter
• DC/AC converter
• Frequency converter
• Filter
