Dynamic grid fault simulator

Modern wind turbines or photovoltaic power inverters are required nowadays to respond to faults in the electrical power grid without simply shutting down. Such a response is called "fault ride-through". The dynamic grid fault simulator emulates such faults in the electricity grid. This makes it possible to investigate the response of any equipment connected downstream from the fault.

The grid fault simulator has the following features:

• Adjustable power failure durations from 50ms to 1000ms
• 5-level, adjustable voltage drop for all phases
• Symmetrical and asymmetrical grid faults can be set up
• Faults can be selected with or without earth contact
• Adjustable start angle fault ride-through analysis
• Graphic display
• Connector voltage: 3 x 400V, 50...60Hz
• Dimensions: 297 x 460 x 210mm (HxWxD)
• Weight: 18kg
